When i'm playing flash video in a browser, for example on youtube, whenever i change my volume or contrast it exits fullscreen. I change the volume and contrast via the keyboard function keys, and a badge showing the new volume/contrast will popup then dissappear. This popup is probably whats causing it to exit fullscreen, but is there anyway to get them to live in harmony. I quite like the popup telling what the new volume is. If there is no way to get them to play nice, how do i disable this popup? I'm using mint 8 main.
