From the developer:
Fixed bug where the speaker mute was being toggled in addition to the microphone mute for the Voyager 510-USB and the .Audio 910.
Fixed crashing bug on Vista caused by trying to access the mixer before it was available.
Added the ability to turn on the headset's radio link and leave it on with the "Lock headset radio link on" feature.
