change in font size after dowloading update

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

Hi all. I'm new to this but after downloading an
update..I think it was ATI technologies display..all the
font sizes have gone too big and I can't work out how to
reduce them. I did try and remove the program which
didn't seem to return to normal but things did seem to
shrink a bit..but recently installed another update and
again things are too big. Any ideas as to how to get the
windows so they stay on the screen?
