Here's a question for the masses. Background info. = I had a bad memory chip from Crucial (they shipped a new one) and multiple file problems. Those got fixed. I've upgraded to 10.4 Tiger, but when I hit F11 to activate Exposé to show my desktop, the application windows that it moves away come back within two or three seconds. In fact, it's not even a consistent amount of time but changes like it's having trouble deciding what to do. It won't keep everything pushed away so that I can see what's on my desktop, move files, etc. My dad suggested another app also has F11 as a hotkey, but I'm not seeing anything conflicting. Any advice? Thanks, and have a super duper day!
