I use this at work. Its fantastic. However, I lock my workstation at the end of the day. When I come back to it, and unlock, MicMute forgets its job. It listens to the keypress I've assigned and says it toggles the mute, but, doesn't actually toggle.
I've had to come up with unique ways to restart the app periodically.
Using Win7 Pro x64.
how are you restarting the app? only thing i found that works is reinstalling
