strange problem, help plz

[StankBacon]

so im not sure what is causing this or if its meant to happen, perhaps someone here has heard of this.

when i press the up arrow, left arrow and right ctrl at the same time, Firefox opens a new window.

now this is a problem because i use the arrows in css (>.>) and when i jump sometimes the game minimizes because a new Firefox window opens.... incredibly frustrating.

i tried searching Google but got nothing, any ideas?

Turn off Firefox before you start playing a game. Problem solved. Or is this happening when Firefox is already not running?

[StankBacon]

it opens firefox even if its not running.

Did you somehow assign a macro combination to those keys?

Don't use bad keyboard layouts for your games.

Don't use bad keyboard layouts for your games.

Bad keyboard layouts like having Space Bar as jump? That never made sense to me since "jump" is pressed more often than "use." And don't bring up the strafe + jump argument because every game has momentum that carries you, meaning you don't need to have both "D" and "jump" depressed at the same time.

E = Jump
X = Use
Space = melee/weapon throw

That aside, this doesn't help him. He shouldn't have to change his keyboard layout just to prevent his browser from opening. That can't possibly be a built-in macro.
