I've had this happen a few times now.  The volume controls in MC just stop working suddenly, and the only way to get them to work again is to close down and reopen MC (no reboot required).

When I say they stop working, I mean that my remote volume buttons cease to function (all other buttons continue working ok), and changing the volume using the mouse via the on screen display buttons in the bottom right of the screen also do not work.

Has anyone else experienced this issue?

I'm using a Philips SRM-7500 remote.
