Hi again, This problem for me is not new. For some reason, when i try to close webpages that open up acrobat reader, it drives cpu util to 100, and takes several minutes to close. Usually i just end up "end tasking" it as its faster. Anyone else have this problem or know whats going on here? Any help would be appreciated, thanks. Btw, im using both firefox 1.0pr and acrobat reader 6.0 on XP pro.
