Black band on right and bottom of displayed image

[aworonow]

I'm running Windows 7, 64b & the current release of PI. When I open an image, early in my processing train, and (importantly???) do a screen stretch, it always has a black band (~3/8" on my screen) within the image border at the far right and bottom. If I grab the image and drag it off the screen then back on, the border is gone. However, it remains uneditable. The cursor is an arrow in this band, and a cross  hair otherwise. If I try to crop the image to the eliminate the band, the dynamic crop box disappears when it enters the band, so I crop inside it, save the image, close the one I have, reopen the just-saved one, and now it has an band down the right and across the bottom too, and it cannot be edited either. Once I've applied a histogram stretch (even just applying the screen transfer function permanently to the image), the problem disappears.
I'm a fairly new PI user, so it's probably my doing--but what is it I'm doing wrong?

Could you upload one of those problematic images?

[aworonow]

this is one...

[aworonow]

Oh, and here is a screen shot of what I see.

Do you have the problem with the crop you uploaded? I cannot reproduce it here...

[aworonow]

Yes, when I load it from the file menu then screen stretch.
I'm using a Lonovo all-in-one touch-screen computer (The NVIDIA board says it is "3D ready." I'm not using 3D and the video board is a NVIDIA GeForce GT 555M.)

Ok I am new to PI myself, but is this not just a single sub after alignment?

If you look at other subs, the black border will be different sizes. This is normal and is cropped off after the final ImageIntegration.

Not quite. This is a pre-star alignment sub. In fact it is the center of a larger frame that also shows this effect. After stacking the exact same boarder is there. If I crop it away/save the file/close the current view/reopen the cropped file, it reappears and eats another fraction off the new image. Until I do a permanent histogram stretch, it is there.

Oh, and here is a screen shot of what I see.

From this screenshot, I'd say that your PixInsight installation has been messed up for some reason (for example, the window icon is not part of the RC5 distribution, and the black regions correspond to invisible scroll bars). For sanity: Please uninstall the application, reboot your computer, and install RC5 again. Let's see if this fixes the issue.

[aworonow]

Scroll bars...I think you've nailed it. I was going to install the new release soon anyway (was in the midst of a processing effort and waiting until it was done). Unless there's a continuing problem, you'll hear no more from me on this topic. BTW, I find that, for the outstanding level of sophistication and remarkable capability, PI is not that hard to learn. Harry's pages and the PI tutorials are wonderful go-bys!

Thanks, Alex

Installed new version: 01.08.00.0997. Had problems doing so, even after uninstalling (via control panel) previous installation. It complained that it could not write C:\Program Files\PixInsight\bin\Annotation-pmx.dll. I looked in the bin folder and it was there, so I renamed the entire PixInsight folder "oldPI" and tried again. Then it installed--new opening screen, new icons and all. But the black bands are still there. Drat!

One additional behavior I just encountered: If I zoom in then out, the band is gone and the margin where it was now is accessible by the cross hair. That's an easy work-around for now!
