I'm running CS5 in Windows 7 64-bit.
I've been running into an odd problem using the Animation window and Transforms. If I select an area then try to Transform it (using either Free Transform shortcut or the Move tool with "show transform controls" enabled), the canvas and navigator stop refreshing. I can still pan around the canvas and draw on selected layers, but those are the only operations that get the screen to refresh. Changing frames, turning on/off layers, and hitting Undo will still perform those actions but the results aren't displayed on screen until I pan the canvas.
If I have multiple files open, all of them are effected in this way. Quitting then restarting PS gets rid of the refreshing problem, but if I use the Transform tool in a file this problem has occurred in, the same thing happens.
This doesn't happen until I've been working on a file for a long time (at least an hour or so), regardless of file size as far as I've tested.
The problem persists with and without OpenGL drawing enabled. I have an Nvidia GTX 560 with driver 306.97 installed.
Thanks for the quick response,
Restarting Photoshop with OpenGL disabled unfortunately doesn't fix the problem.
I left a topic of this issue on the NVidia forums, and might try updating to the latest driver.
Just updated the driver to version 314.07 and PS is still behaving the same way. I don't recall getting any errors with my drivers, either.
I opened the same files that have been giving me trouble in CS4 as well, and it's the same problem. I don't know if this problem is memory related, but purging the cache didn't fix it either.
I've never experienced this problem outside of using the transform tool with the Animation panel open, and ram/disk space haven't posed any problem on my setup. Any suggestions?
