This didn't USED to happen, but it seems whenever I'm working in Illustrator CS, after a while the folder containing the open file will become littered with temp files ("Acr17442512.tmp" and such). Aren't these supposed to get deleted when I close the file, or quit Illustrator or something? The strangest part is that the exact same thing started happening to me on the Windows version too. Could it possibly be just the particular files I've been working on? It's annoying to have to throw out a handful of temp files almost every time. (I'll be installing CS2 before long, but I don't know if that will change anything.)
