This is the firest time I have ever encountered the Compatibility message. It seems Windows sees the program as being an old one.
Here's the Events Report.

I'm running CS6 on Win7.
I see the old bugaboo ati is indicated, and is most likely the cause, yet the appearance of the compatibility report is new.
Earlier, I had a problem using the Quick Selection Tool. The screen went black instead of showing the cursor. I had to quit CS6 and restart to fix it. An hour or 2 later, this crash.
I expected that. Unfortunately, I have another program that reqires OpenCL to operate at a reasonable speed, which I use for batch processing of certain data. 12.2 runs as a slug with that program. 24+sec per image vs 7 sec with 12.4.
Rock and a hard place. Maybe 12.5 will fix things.
Chris, what did Windows actually do with respect to a compatibility fix?
