Ok, So I am running Tiger 10.4.2 and I have been having some issues. Most noticeable were iChat kept signing me off (AIM) and exposé show desktop was not working (hot corners and keyboard). I decided to archive and install Tiger again to try and fix the problems. I did repair permissions and inserted the DVD. Archived and installed. Started off ok, did all the sw updates, but now iChat beachballs on me (after it goes through all the set up info). Mail is laggy, Safari is having trouble resizing windows, exposé show desktop is still a no go and my Apple wireless mouse is not being picked up (it can click but the computer won't let it move around). I already inserted the DVD again and did a repair disk, found nothing. Ideas on how to fix this problem before I call Applecare tomorrow? Also I am running a 1 ghz iMac G4, 768 RAM, 17" screen.
