Hello there,
I am having some issues, nothing severe with WB 6.2 on 64 bits Vista. I am running Azureus Vuze in the background most of the time, to seed my torrents. When I start World of Warcraft as a example (Call of Duty 4 has the same issue) the game goes to fullscreen and then blasts me back to my screen. This happens only when Azureus Vuze is in the background (tray, or minimized in taskbar). So when it's fullscreen I can play my game fullscreen too, like there is nothing wrong. Not sure where the issue lies. Several WB themes do the same thing, not there when WB is off.
Cheers,
