I know that there has been some discussion on this topic, but I am unable to get my AimTrak to reload by shooting offscreen.  I have tried different combinations in the Aimtrack config settings, but nothing seems to work (I have set trigger, both on and off, to the same button.  I have even set one, or both, to various mouse buttons).  By the way, the trigger activates button 2 in the windows control panel (I do believe that it is working properly).  
In mame, I do not believe that there is a way to assign a specific button that equates to shooting "offscreen" (and yes, I have "shoot offscreen" set to "1" in Mame's config settings).  However, I know that people have gotten games, such as Lethal Enforcers, to reload by shooting offscreen.  By the way, if I play Lethal Enforcers with the cursor toggled on, there is no way to
 completely remove the cursor from the screen (even when I am aiming way offscreen).  But I know that there is something that you can do in the Aimtrak utility to overcome this.  Please help...it's no fun for your game to be over after shooting just 6 rounds.
