P: Crashes on zoom (win)

Do the crashes still occur if you disable Rulers?

Thanks! Here are all 11 reports the Reliability Monitor shows: https://www.dropbox.com/s/ko1r75xujmq...

Tried this. The crashes remain. Perhaps one of the conditions is that I have the Ruler tool on when zooming in and out. With Ruler on and zooming, PS crashes steadily both with "Use Graphics Processor" on or off.
Also, with graphics processor off I got weird undo behavior: first undo (ctrl+z) works, the effect of the next undo (ctrl+alt+z) becomes visible only after I click the screen.
And at some point of working without graphics processor, all elements on the screen became transparent https://www.dropbox.com/s/419f6okt8vd....

We may have a temporary workaround for this.  Trying going to Edit >
Preferences > Performance and uncheck "Use Graphics Processor".  Quit
and restart PS.  Do the crashes stop occurring?

Look in the system event viewer, or in reliability reports.
The detailed crash log will have the name of the faulting module.

Windows 7. Where do I find the crash log? The message when Photoshop crashes says something like "Photoshop has stopped working. Debug/Close".

What OS/version are you running on? What does the crash log/report say in it?
