It would seem that on both my laptop (XP) and the XP partition of my desktop (which is essentially my MxO-and-nothing-else partition), when I mouseover any item, the usual description box does not want to show up.  My drivers are up to date (nVidia GeForce 8800GT, 178.24 on the desktop), and I'm not experiencing any other issues.  Any help would be appreciated!

Nevermind, easy settings fix.
