running vista 64bit with ATI Radeon 3200

i use atis ccc or display properties to troubleshoot display problems.

my issue is that some programs or windows that show up on my desktop are to large for the screen. i can take the time to resize some but however others i cant because they're windows to installing programs or other non adjustable windows.

ive changed my screen resolution numbers of times to see which display would work best, however im getting no answer to fix my problem.

help please?
