Odd as it may seem, I use the left hand "side located" mouse button during computer gaming to activate the microphone when using Teamspeak. That's not the LMB (at the side of the RMB), but button 3 (which you use in browsers to go back a page. You know which I mean...

Anyway - the problem is, that when in game, if I press the button to speak to other players whilst in the game menu screen in both Call of Duty, and most recently the Battlefront Star Warts Beta, it does like it would if I were in a web browser and moves the game menu screen back a page.

I really need a way of stopping this happening, and no, the option is not one of not using said mouse button. Maybe a macro command or something?

My mouse is the Corsair M65.
