PTT key (mouse button) doesn't work after Standby

[Sgt-Nukem]

I've set my PTT key to "M:Button 4" (i.e. "browser-forward") which works fine.

However, after going to Standby and resuming later on, the key is not accepted anymore as PTT function.

I have to open Settings...->Shortcuts and just click "Apply" again to let the key-hooking proc work again.

AFAIR this worked fine in Mumble 1.2.9 something.
