Multiplayer menu's screwed

When I press tab online, this happens (see screenie). It get’s stuck on the screen and I can’t view the other players. Also, when I try to access my spawn menu, I can just barley see it in the top left hand corner as pictured. Could someone take the time to help me with this?

Also, my specs:
Processor: AMD Phenom 9650 Quad-Core 2.30 GHz
Graphics: Radeon 4890 HD
RAM: 4G’s
OS: Vista 32bit

Delete some addons then reinstall them STUPID GMOD UPDATE… this happened to me too.

Uh, not quite sure what update you’re talking about. I haven’t downloaded any addons for a long time as well…

This happened to me in a friend’s server. When the only addons I have is just a bunch of L4D models. And my download filter is set to none, they also said they didn’t have any custom scoreboards either. But my spawnmenu seems to be fine, except for the fact that some tools don’t work and get sorted to a new category for some reason.
