We have released an update to the beta for both games, fixes include:
  • Fixed alt-tab not working correctly, the game window is no longer forced on top
  • Added "cl_mousegrab" cvar, if set to 0 then the game will not grab the mouse. This may be needed to enable alt-tab with some Linux window managers. You can also add "-nomousegrab" to your command line to disable mouse grabbing.
  • Fixed error on launch loading mss32.dll under Windows
  • Fixed hang on startup causing a black screen to display on OS X and Linux
  • Update Server Browser display to match behavior of Source engine products
