Minor issue with Aimtrak/Arcadeguns.com gun

[ASULutzy]

This is more a minor nuisance than a real complaint, as it does happen infrequently, but if there's anything I can do to ameliorate the problem I'm all ears. Basically sometimes when I very quickly jerk the gun off screen and shoot to reload and then drag it back to the playing area, the mouse cursor will still think it is off screen and repeated shots while targeting on screen enemies will just continually reload the gun.

It's not a huge deal if you're playing with MAME crosshairs on, but if you turn them off it can be hard to realize it's happened till it's too late and you're getting shot. Any tips to reduce this problem, even if they require modifying playstyle?
