"Nonempty processing histories"

[TinySpeck]

Hello everyone,

I'm a brand new PI user, working through my first image.  I've set up a PI project for that, and gotten through stacking and background neutralization.  I'm saving gigabytes of intermediate files to disk.

When I went to save and exit PI last night, though, I kept getting dire warnings something about "nonempty processing histories" associated with unspecified images, and how I would lose them if I quit.  I thought the latest PI saved your entire project, including histories, but it didn't seem to be doing that for me.  I even dragged the History of the two images I had up onto the desktop and did Save Process Icons, and that didn't help.  I ended up quitting PI despite the dire warnings.

When I re-started my PI project this morning everything looks intact, including my images and saved process icons.  Without touching a thing, I went to close PI and again got the "nonempty processing histories" warning.

What do I need to do to exit PI gracefully?  Any why doesn't it seem to store my processing histories?

Thanks much,
Gerrit

i think PI just doesnt track whether or not any image has been modified since the project was saved. so if you save your project and immediately quit, you will be fine as you found.

if you dragged the processing histories to the desktop after saving the project and then quit, that is why those icons were lost... they were never saved.

@pfile -- PI does say that even though no images have been modified since being saved, they contain "nonempty processing histories" which will be lost.  Even when saving the project and immediately quitting, I get the warning.  When I create image process histories and save them, then save the project and immediately quit, I still get the warning (and no icons are lost either).  And this morning I did nothing but open the project and immediately exit PI, and STILL got the warning.

How should I exit PI so that my project is safe and I don't get these warnings?

When you save a project, look in the process console. If there is a message “ Project saved OK”, then all is good. Just ignore the message. It’s just giving you additional options.

the project is safe, the warnings are wrong. im not sure that PI distinguishes saving and image as a standalone file (which does not save the processing history) and saving the image as part of a project.

i guess this is a bug, but its been like this since projects first appeared on the scene.

It's a big warning with a yellow caution exclamation point and says:

"No image has been modified, but there are nonempty processing histories associated with one or more images.  Unsaved process instances will be permanently lost.  Exit anyway?  (Boldface is in the warning.) 

There is nothing the user can do about this, there is no indication of what image may be affected, and I wasted a half hour last night searching the web and trying to exit PI without "permanently losing" information.  This is awful!

One of the big claims to fame of the latest release is how it saves every scrap of your project, so this warning is doubly alarming to a newbie.  Wow, I wonder what other surprises I have in store.
