Mumblease

I am using WIN 10 and Mumble 1.3.4 downloaded from https://www.mumble.com/mumble-download.php. Also tried 64-bit version from https://www.mumble.info/downloads/, same results.

Push to talk is not working for me, I've tried multiple shortcuts mapped to my mouse and keyboard. However, when I display the push to talk window and click in it people can hear me me just fine. Other wise everything regarding my microphone is working properly. Anyone have any suggestions or fixes? Thanks, M
