99% CPU usage after closing Front Row

Every time I quit Front Row I notice in Activity Monitor it's still running with 99% of CPU usage. It happens both quitting with Cmd+Q and pressing Escape until reaching the main menu and then back to the desktop.

The weird thing is that I read about posts related to this issue on forums found with google dated years ago, and no one with a solution: so, is someone still experiencing it? did anyone find a solution?

thank you
