Windows XP Home Edition SP2 Glitch

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

I would appricate any help provided.
Almost a year ago I downloaded the SP2 to my pc direct from microsoft
website. For the most part my pc & my XP Home Edition works fine except that
what ever screen or webpage or email or anything I'm doing the the screen
that I'm on tends to de-highlight. I'm not sure if that's the right way to
discribe it. I have to keep clicking the mouse some where on the screen I'm
working on to make it the again the main screen I'm on. I hope someone
understands what I'm trying to explain. It is very fustrating. Also there
are times where I'm running different programs and then everyting freezes. I
have sent error report on this to Microsoft, but they don't seem to have a
clue.
I really would appreciate help. Thanks.
