Command key on Mac activates Push To Talk button

On a Macintosh, the "command" key is used for switching applications (like alt-tab in Windows) and for cutting and pasting (like cntrl-c, cntrl-v in Windows). However, in Paltalk Express, just hitting the command key will automatically push the "Push To Talk" button in a chat room. So I will just try to switch applications and accidently jump on the mike and annoy everyone in the room. This makes Paltalk Express pretty much unusable for people on a Mac.
