I have a blackbook running 10.6.4 with a GMA 950 that I use dual monitors with. If I use the extended desktop mode, and drag a safari window with a flash player onto the external display it will freeze and become unusuable (can't interact with it). The audio will still play through the speakers, and dragging the window back onto the main display brings back the flash functionality. This is a fairly new problem, it never used to happen before. Any ideas why? UPDATE: It appears to be a Safari 5 issue. Anyone else experience it?
