How do I fix Flash issues?
I have tried the fixes in Full screen Flash problems and Video's won't go into full screen and none of this solved my problem.
In YouTube, if I click quickly on the "full screen" button many times, eventually it will "stick" and stay in full screen. But I am watching a different flash video player (URL: http://www.ewtn.com/Live/unicorn/jwplayer.asp?feed=domeng) and no matter how many times I click, it won't stay in full screen - it flashes briefly and then collapses back to a window. Ubuntu 12.04; desktop Unity; browser Chrome 18.0.1025.168 (Developer Build 134367 Linux); Flash - "Version: 11.2 r202" NPAPI.
