I'll be sending you a minidump link over pm lummox.

I noticed I'm not on the most recent version, so i'll update and let you know if it happens again.

I looked at the minidump, but it turns out to be rather useless. The stack trace info it gave me was this:

Looking at just the first three frames, they don't all line up properly with instructions in either 1402 or 1401.

I'll try to get somewhere with your non-dump trace from 1402 tomorrow and see if I can tease anything out.

Looking at my downloads folder, it was 1400, not 1401, i had already updated by the time i was making the post, so i couldn't check to be sure.
Jan 12 2018, 10:00 am
Okay, knowing it's 1400 is a big help. I've finally been able to get somewhere on a trace and it appears to be an issue with images. Looking into it further.

I think I found where the hang is occurring. How it gets into this state I can't really tell, but a simple sanity check should be able to prevent that state from causing the hang.
