Hi Juan... I just realized that the two files enclosed with my last post may not be adequate for diagnosing the Process Explorer problem since I did not include an .ini file for the instance with Process Explorer was working correctly... So I went through the steps again and have enclosed a .zip file containing 1) the file, "1-WithProcessExplorerProblem_PixInsight.ini", for the instance with the Process Explorer problem, 2) the file, "2- RestSettings_PixInsight-20190103181355.conf", created when I used the Reset Settings, 3) the file, "3-ProcessExplorerNormal_PixInsight.ini", for the instance with Process Explorer working normally, and 4) the file, "4-ProcessExplorerProblemRecreated_PixInsight.ini", for the instance with the Process Explorer problem re-manifested (after clicking RESOURCES>Learning>Online Video Tutorials). Your attention to this matter is much appreciated.

Hi Gerald... Thank you for your reply. I understand that work around and tried using it, but even if I start running a second instance of the PixInsight core executable and close the first instance, if I try to use the link to the "Online Video Tutorials", the Process Explorer "Black Window" problem resumes... So until the PI Tech Support can resolve this, I will go back to using PI 1.8.5....

Hi Juan... I just installed the latest version of PinInsight, version 01.08.06.1457, and it continues to have the problems with Process Explorer. If I move the cursor over the Process Explorer tab, the window goes black! When I click on "RESOURCES", then "Learning", then "Online Video Tutorials", the window also goes black... The so-called "work around" don't work...Can anything be done about this... I would really appreciate your assistance in resolving this issue.

Hi Susan!
You are right, also on my Win7 Prof Notebook (with propriatary grafikcard) the same happens.
In addition opening a second instance of PI does not help anymore in the new Version of PI -

BUT

there is still a possibility to very simply overcome this little issue.
Good image proprocessing can be done ONLY when the histogram is open all the time to keep control
how the histogram of your image develops during processing.

So,  the FIRST step in image processing is to open "HistogramTransformation" from the top tool bar "PROCESS"!!!!

Now, whenever the screen gets partly black, i click over the Histogramm process window and everything is back again.
I never click the Process Explorer in the vertical tab as i prefer the PROCESS selection in the top Tools bar.
So this happens anyhow never when using PI 1.8.6

Concerning the Video tutoriasls - yes i have the same issue but  they can be be opened in an extra Internet window.
I dont see this as a bug in PI, i see this as weakness of my grafik Card in the Notebook.

So, for me the go around is a very small issue and i dont have to miss the Advantages of Pi 1.8.6.
There is no reason for me to go back to 1.8.5

Hi Gerald,
My OS is Win10 and after struggling for hours with what seemed to be a corrupted PI I was about to give up and restore the previous version when I spotted your tip about leaving HT open. It also works for Win10. I will continue to try it but so far so good. 
Many thanks,
Pete

Hi Susan,

Thank you for uploading the .ini files. Unfortunately, there is nothing in them that can help to identify the problems you are experiencing. Both files, before and after the problem, are basically identical. The only differences are in some window positions and dimensions, which are completely irrelevant.

Susan, Gerald, Pete and the rest of users that are experiencing these weird problems on Windows,

I am very sorry to say this, but I am afraid these problems may have no viable solution. They are machine-specific issues that are being caused, with very high probability, by faulty graphics drivers. Previous versions of PixInsight managed to work with these drivers, but version 1.8.6 is much more demanding of a valid working environment, which exposes their failures. Unfortunately, there is probably no way to update these drivers because there is no longer active support for Windows 7 in many cases. Microsoft ended mainstream support for Windows 7 on January 2015, and will discontinue its support completely on January 2020.

So there is basically nothing I can do to solve these problems. I cannot reproduce them on any of our machines running Windows 10, where the latest version 1.8.6.1457 of PixInsight works perfectly (modulo pending bugs). As I have said many times, if I cannot reproduce a nontrivial problem, I cannot understand it and hence cannot solve it.

Finally, please realize that these problems are very, very strange. PixInsight does not do anything remotely similar to what you are describing on any platform under normal working conditions, including Windows. These are the kind of weird issues caused by misbehaving graphics drivers or hardware. Please don't take this as an offense—nothing farther from what I'm trying to say—, but the workarounds you are describing sound esoteric. If they work, that's probably just because they are 'moving' the problem to a different 'place', but, heck, if they work, go ahead!

Those who know me also know well what I personally think about Windows. I don't want to start an operating system war here, so I'll better stop elaborating more on this subject. I just would like you to realize that Windows is intrinsically a problematic operating system, especially for a complex multiplatform application like PixInsight, and even much more problematic on relatively old or outdated hardware. Installing the latest Windows updates is important to guarantee system stability, but unfortunately some Windows updates contain bugs and generate conflicts that lead to the opposite result. Some applications may replace system components with invalid or outdated versions. Some virus protection applications may interfere with the normal operation of applications, or even modify components of installed applications. The proliferation of bloatware and malware is another cause of endless problems. And I could continue with the enumeration until boring you...

The current version of PixInsight works remarkably well on a clean Windows 10 installation. Irrespective of my personal preferences, I try to do my job the best I can, and producing a stable Windows version of PixInsight is undoubtedly a crucial part of it.

Hello Gerald and Juan,

Gerald, thank you very much for your suggestion. I reinstalled 1.8.6, opened HT from the top tool bar "Process" and can now work in PixInsight, manageably, by leaving the HT window open, as long as I can keep the cursor away from the Process Explorer Icon on the left hand Explorer Windows tool bar ;). I wish there was some way to close Process Explorer, from outside the Process Explorer window. Then it wouldn't show up in the Explorer Windows tool bar on the left.

Juan, thank you very much for your feedback, clarification, and all the hard work you put into fixing PixInsight for us "lowly" users. I didn't realize Microsoft will discontinue Windows 7 support completely on January 2020! YIKES! THAT'S ONLY A YEAR AWAY!... SO, I have a better understanding of the situation... I guess I am just going to have to bite the bullet and replace my circa 2014 Windows 7 based HAND-ME-DOWN Thinkpad laptop for a Windows 10 "latest and greatest"... (sigh)... My husband is NOT going to be happy with me, but OH WELL!

At least, for, the time being I can use PixInsight 1.8.6 as is (thanks to Gerald's suggestion).  :)

Re: NO Problem with installation of PixInsight 1.8.6 on Windows 7 Prof

Hi Juan!
Thanks for your explanations. For me this is not a PI issue.

I do have a main PC with Windows 7 Prof and an extra high resolution and 2 large displays supporting grafik card.
The latest Version of PI is running on it without any malfunction as always!!!!

So from my experience, as my notebook is a massproduct which usually gets cheap and not full functioning grafik card, it
is an issue of the hardware which misses profund grafik support internally.
On better HW-equipment everything runs smooth and easy.

I did not complain,  i see it as my mistake when i bought a somehow cheap prebuilt notebook.
And i only wanted to help Susan.

Your fully with PI satisfied
Gerald

Hello Juan and fellow PixInsight users...

I wanted to give an update on the issues that I was having with PI 1.8.6... The problem I was having with the Process Explorer tab has been resolved!... I went ahead and upgraded from Windows 7 Pro 64bit (on my ThinkPad T420 with 8.00 GB RAM, Intel(R) processor Core(TM) i7 2620M CPU @ 2.7 GHz and Intel HD Graphics 3000) to Window 10 Pro 64 bit (by doing a clean install) and PI 1.8.6 now operates perfectly. And I didn't have to go out and buy a new computer! :D The problem was the operating system. Juan is right. PI 1.8.6 is optimized for Windows 10.   

If any of you have been experiencing the same problems as I was, I recommend that you bite the bullet and upgrade your operating system to Win10. I was dreading having to do this myself, but discovered, from some online resources, actually how easy it was to go through the process and not have to pay a penny for the upgrade... I upgraded a laptop and my Observatory PC from Win7 to Win10, both clean installs, in one day. I was quite proud of myself...  ;)

Regards,

Susan

Hi Susan,

I am glad to know PixInsight is now working on your reinstalled machine. Please don't hesitate to report other problems if they arise.

Thank you so much for reporting your success experience. Knowing the things that don't work is absolutely necessary for us to improve, but knowing when they work is great ;)

Yup - just hit me with installing PI-windows-x64-01.08.06.1473-20190514-c on my laptop which runs my scope.

Seeing the disdain for customers from the developer is unfortunate.  'Windows stinks, we only support a clean install of the latest Windows 10...'

Nearly half of Windows users still use Win 7.  You are writing off half of that user base.  Think long and hard about your customers.

Not everyone can have the latest toys.  I guess now I can't even have the toys I paid for.
