Just updated to Firefox 5 and noticed a problem. When I load a ustream.tv site on the main monitor, drag it over to the second and click the full screen button it shows up on the main instead of secondary monitor. I tried Hulu the same way to make sure and it worked as expected on the secondary monitor. For some reason Ustream.tv 'full screen' in showing up on the wrong monitor. I was using the latest Firefox 4 and had no problems. I'm using a Geforce FX5700 Nvidia with dual view and have the latest Flash player installed. Thanks.
