a fix for annoying cstrike problem regarding menu screen

I don’t know about the rest of you, but whenever I try to create a listen server (lan game for example) I always tend to have a part of the menu background pop up in my game, I always have to press esc and resume to erase this.

I’ve been doing that for like 3 years now, and i’m wondering if there’s a fix for this common (i think) problem.

I run cs in OpenGL 1024x768 mode, and obviously the menu screens are 800x600 (that’s the size that i can assume takes up the space)

please let me know if there is a common remedy for this.
