Upgraded to windows 10 from win7 this weekend and have a curious issue with push-to-talk.I use a Microsoft sidewinder mouse with one of the side buttons configured to activate push-to-talk ( } key is used).

This worked fine with win7 and kinda does with win10 .if Im playing wow or on web page or in any other window its fine. But if I have the Teamspeak window the button stops working, if I switch screens it's fine.it just doesn't work when teamspeak is up. The keyboard keypress works but the mouse shortcut/hotkey doesn't. Lucky it works in game but pain as I have to use keyboard if configuring TS or having a chat out of game.

Any ideas? Running 64bit version on PC and teamspeak is running as administrator.
