I just purchased two of them and when I calibrate them the mouse cursor is on point and is calibrated fine, but when I open up Area 51, time crisis, etc, pretty much any shooter in MAME, the crosshairs are a few inches off where they were just on my desktop screen. They also jut across and not smooth like they do on the desktop screen. Anyone know how to fix this?

I have a BenQ MLG LED monitor and windows 7 professional 64 bit
Also, another issue I'm having is the gun doesn't reload when I shoot off screen. I have shoot offscreen checked in the controller settings in MAME, do I need to set it individually in the game as well hitting the tab key, and if so, where? Cause I don't see it.
