I have a unique problem.

In DDO when you press the middle mouse button use the turn keys on the keyboard, your character will spin in place. I want to disable that feature because I use the middle mouse button as my PTT button for voice chat , and often when talking and moving, I will get similar effects as the "mouse look" feature (I also have that disabled).

Before someone suggests that I change my PTT button, I have been using this configuration for 15+ years on every game I play and this is the only one that has caused a problem. I am an "old dog" and I don't like to learn new tricks.

Can anyone point me to the ingame setting that will disable my middle mouse button making me spin in place?
