This happens once every few days, typically when I go to either mute or "un-mute" either via the bottom of the screen taskbar or the taskbar at the top of my keyboard.
Everything in the taskbar, including the Start menu becomes unresponsive. Sometimes after choosing to "restart" Windows Explorer, it works. Other times, I have to restart the computer.
Any ideas?
Strange thing is that this error occurred both in Vista 64-bit and now with Windows 7 Home Premium.
Thanks in advance,
Chris
