Hi All This has nothing to do with the recent update, it started before. Since playing WOW in Leopard I have had no problems or niggles until now, earliar today a niggle started. I play WOW in its window mode, earliar today on starting WOW the game screen opens with a black screen although you can hear the sounds. If I then just move the game window ever so slightly it all comes to life and from there on in all is OK. Booting WOW into full screen mode is OK right from the start, if after booting into full screen I switch to window mode, window is black until I move the window slightly, or I drag another window over the top, and as I move that window around over the WOW window the graphics fill in. As I say not a real problem just a niggle, and was just wandering what the cause could be ?
