While watching streaming video content, Youtube for example, and I click on the fullscreen button, the screen goes white.

The video plays fine but when I try to watch full screen, the whole screen goes white. The right-click menu comes up and I am able to chose one of the options but the corresponding window does not appear the screen remains white. If I click on the screen the video stops and starts (I can tell by the sound). The escape keys returns the video to the normal size within the browser page and the window for the option I chose from the right-click drop down menu appears over the video.

Flash and other of your plug-ins look a bit dated, please review Updating or re-installing your plugins, perform a plug-in check and update as needed.

See if the problem still occurs with the latest Flash version.

That totally worked, thanks. The problem now is that it seems that the refresh rate is out of sync, like when you see a computer monitor filmed on a news cast. Any ideas?
