Unconfirmed error (Reported by 2 users)
Push to talk works fine when Teamspeak window is on top. When the user is in-game (World of Warcraft) and Teamspeak window is in background, push to talk does not work anymore.
Solution: Do not run other or any application in admin mode! They can block the access to the hotkeys for all other software which does not run in admin mode.
