[CentOS] Flash problems in newest upgrade?

Hi, I just upgraded to the newest kernel and Flash. Hulu now "grays
out" when I try to go to full screen. I tried uninstalling and
reinstalling the proprietary video drivers (no difference either way),
so I'm guessing it has something to do with either the new Flash or
the new kernel. Anyone else experiencing this problem?

Thanks for any pointers.
