New GFX driver problem

[Kedeli]

I just updated to the latest ATI drivers for my HD 4870 and now I can't watch videos in fullscreen on youtube? Anyone know why this is?

Update/reinstall your Flash player, if that doesnt work reinstall your gfx drivers.
Theres a conflict in there somewhere more than likely you have an older version of flash which doesnt recognize the new gfx drivers.

Thanks
