(thanks STG!  ) I have finaly got pc games to launch from my mala frontend.

But now there is one small problem. When i play a pc game, instead of the menue dissapearing until you exit from the game, the menu will reapear before the pc game starts and the attract video/menu music will still play behind it, which not only is annoying with the sound overlapping the pc game. But the video playing also slows the games frame rate down... Is there anyway i can stop this from happening?
Atm im stopping this being a problem by disableing the videos and music, but I really would not rather have to turn the videos off or only use a picture for each pc game on the list   

Does anyone know how i can fix this?
