I'm seeing it here with no Wacom drivers installed. I'm seeing it mostly when I undo (I wonder if it's arbitrary and everyone's just attributing it to the most frequent thing they do? ) though I have seen it with the clone stamp and one time, the same 3 clicks with the polygonal lasso would cause it repeatedly. Specs: Imac8,1 (which prior to reading this thread, I assumed was the problem), 3.06, 6 gigs of ram, plenty of scratch space. I turned off background save and thus, auto-backup save, thinking that might be associated, but it doesn't seem to be as it hung shortly after that. As I said, no Wacom drivers, but I am running USB overdrive to control my Logitech mouse. When it hangs, it pins a processor at 100% for some amount of time, and if it's left alone, it seems to me that it might go on that way forever. If I switch to another app, then back to PS, it keeps hanging, but after some amount of time, switching back to PS seems to be what un-hangs it. Maybe my imagination... I'm in Seattle, you really want to see this? Here's a sample from Activity Monitor from a few minutes ago.
