ScoreDoom mouse question

Is there a way to disable mouse movement in ScoreDoom? I want to be able to look left and right with the mouse and forward and back with keys. I basically have it set the way I want and I can look left and right with the mouse but when I move the mouse forward and backwards my character will move a little forward or backward. It's a little annoying.

Since it's based off ZDoom, the explanations here should apply. You want to turn on "always mouselook".

Awesome. I figured it out. Thanks.
