Combat Arms crash after round end

Combat Arms crashs after map load or after a certain repeatable function. Fix: Turn off Mumble Overlay. If that does not work turn off any program that uses directx rendering, e.g. Steam, Mumble, Xfire, etc. Thanks to Snipes for the solution. Also, if you are using Xfire voice chat and playing Combat Arms, this could also trigger the bug. Seems to be triggered by Combat Arms' change from one part of the program to the other when the screen goes black after the round ends to go back to the menu. Most games to not do this and apparently there is some sort of rendering break that causes other programs to interfere with the process and make Combat Arms crash.
