is there somthing you can do to make PS aucto save your work if you have to end now due to not responding? cause im tired of having to restart
jimma has some sound advice, i mean it is only a quick button hit... my advice is to check drivers/hardware for conflicts, and maybe if all else fails get a new PSU.
I agree with .xelink on that, but the Amount of RAM could also be a problem, how much RAM Do you have?
fresh reformat also never hurts, removes pointless clutter file corruptions etc. has photoshop always acted liek this or just recently, if always then it could be a bad install. only time i get erros with photoshop is when I go to shut down windows with PS still open, though I've experienced that on every system I have used, those at school, several I've built upgraded etc. and yeh..
it happens to my comp to when it does that just wait like 2 min and it will respond again ps just slows u down for a bit and then it stops and goes fast again
try re-installin, delete folders through program files, then do a regclean. if its still not responding, ram upgrade how much ram have you got?
