Adobe3DAndVideoServer.exe stuck on (using full CPU)

Hello,

Upon upgrading to CS5, the CS5 bridge launches a process called Adobe3DAndVideoServer.exe *32, and it's pegged at 25% CPU usage (on my quad core workstation). It appears to be simply stuck at full-CPU cycles without doing anything. It launches when I launch Bridge CS5 and doesn't go away unless I manually kill the process in the Task Manager. I updated my one ATI video card driver, but it didn't fix it.

Any suggestions?

thanks!
