I just found out that Quicktime crashing when loaded in a Firefox/browser on the secondary rotated screen is primarily NVidia’s fault. Apparently when you rotate the screen, the driver does not enforce hardware acceleration on that screen. Joost, Flash and games are choppy when played on my secondary rotated screen. The bug exists for at least 2 years, and a freeware utility that supposedly helps setting the right attributes to Windows to use acceleration, it doesn’t. ATi’s driver didn’t have this dual-monitor/rotation bug (it had others).
