Megatouch Touchscreen Issue

[Maverick]

I have a Megatouch that is having a touchscreen issue. The screen seems reversed. I've gone to the calibration screen in setup. I can click on the cursor points but then when it asks me to drag the cursor around the screen, the cursor won't go the direction I want. When I attempt to drag the cursor to the left, the cursor goes right. When I attempt to drag the cursor down, the cursor goes up. Once I leave the setup menu and go back into the game, I can press on a spot on the screen and the it thinks I'm pressing in the complete opposite point on the screen i.e. Upper right is now lower left and vise versa. Is there a setting I'm missing?
