Hi again,
Here's a little more info from my post yesterday. Firstly, I should have said I am using v3.36.3158.38068 (same as original poster Rick), and my OS is XP Pro up-to-date (same as Rick). Thanks AmadeusX - I tried saving to a different location but results were the same.
To try to show the weird nature of the problem, here are results for four original files (2 have the error and 2 don't). You can see that even though IMGP1614 is bigger than IMGP1785, IMGP1614 is OK and IMGP1785 has the error. I then used Xnview to save the files (the ones with the '-2' suffix) with JPEG quality set to 100% but no other changes. Now IMGP1614-2 works even though it is much bigger than IMGP1785. And even though IMGP1785 increased in size in going to IMGP1785-2, it went from having the error to being OK. All files are 3008 x 2000 pixels.
File Size File Name Works?

The problem seems to be related to some combination of pixel size and file size. Rick's fail with < 1MB files, but over 8 megapixels. Mine fail with > 2MB files, but just 6 megapixels. Unearthly is playing with 40 megapixel files (!), not sure of file size. I'm confused. Are we the only 3 people with this problem?
