Internet Explorer Window Cutting off Text!

When a new window appears (the pop-up kind without an
address bar), the window is not large enough to view or
work in. There are no scroll bars and I cannot drag the
window to enlarge either.This also happens on some pages
when I have to use a drop down menu and only half of an
option appears (ex: "About U" and it is supposed to
say "About Us") I have gone into the Tools>Internet
Options>Advanced and checked those settings, but nothing
changed with that. I checked the View>Text Size, and it
is set to smallest. I checked the
Display>Properties>Settings, and the font sizes are all
small. I have done the Internet Service Pack 6 update and
the problem has not gone away. This problem is occuring
in various websites.

Please help!
