weird graphical changes

I have a weird problem. When I start any MS Office program (Word, Excel,
etc.) the picture/banner thing that comes up as that program is loading has
totally changed. Instead of being nice and fancy, it's really simple and
boring now. Please take a look at the screenshots I have taken because this
is hard to describe. Another change is the white square background behind
the words in the menu bar at the top of some programs. MSN Messenger and
Windows Media Player are the ones I noticed were affected so far. Again,
take a look at the screenshots if you don't understand what I mean. I don't
know what caused this but it started right around the time I installed a gif
editor and a gif animator program. I have uninstalled both of those and no
change, and also uninstalled and reinstalled MS Office. This is rather
annoying and I have no idea how to fix this so if someone could tell me how
that would be great. Thanks.
