Tribes 1 Legendz

So I am using a 43" TV when I am doing some work and I would like to be able to play Tribes on it from time to time. However, when I start using the TV, and I start Tribes on it, Tribes will display in a much larger resolution, and will not play properly, it will not allow me to move the mouse as it snaps to a point that is off the screen. I have tried to start it in windowed mode and I get the same problem with the mouse, it will just snap to a point outside of the screen, it will not allow me to do anything in Tribes.

TL;DR: Tribes will not open properly on a 43" Screen. What the fuck, man. Lol.
