cannot maximize flash video in firefox

for some reason if firefox is open for a few minutes i cannot maximize the flash video, I just get a blank white screen. But if I close out all of my firefox windows then start the video I can then make the flash video full screen. This happens with everything, youtube or any other site. Does anyone know why this happens and how to fix this? I use openuse 11.1 64 bit gnome

Are you using desktop effects. May be try with it off?

how do i do that?

Are you in kde or gnome

actually I do not have desktop effects enabled
I also tried reinstalling flash which did not help, I am using adobe flash, i am considering just reinstalling suse

Totally not necessary.

Try different browsers and different flash sites.
