okay, so ive been experiencing this weird lag problem in cs6 lately. it pops up from time to time. every thing lags, even with small picture sizes like 1000x1000 px. the only thing that doesnt lag is pressing (this is on mac) cmd + z, wich undo, and then redo every time you press it. mac users should know unles youve changed the shortcuts. pressing cmd + alt + z, (undoing multiple times if im not mistaken) does lag though. please help me im going insane!
