Can't get Light Gun to work in Mame

I have an LCD Top Gun and I'm using Mame32 Version 0.104u7.  I also have a trackball and spinner (both USB) which I suspect may be part of the problem.  The light gun works fine in Windows, but is not recognized in Mame32.  I have enabled both mouse input and Light Gun support in MAME32.  I figured I needed to go into the game setup and setup the gun, but when I go into the controls section and I want to change the player one button to my trigger, the trigger pull is not recognized.  I've searched around for answers but haven't come up with anything.

I had the same problem....screen would flash but no hit registered and MAME would map the button click....ended up returning the gun and getting a new one

After reading the above post it made me think it is not the gun, because it does work in Windows.  I tried a simple test to remove the USB spinner and restart the cab.  After that the gun was working in MAME.  javascript:replaceText(' :applaud:', document.forms.postmodify.message); 

I guess this is really a USB / MAME / XP issue as I believe XP doesn't statically assign the same USB inputs every time. 

What is the best way to trouble shoot this and get it working?

IIRC, lightgun option is not needed in XP, and if enabled, forces the lightguns to be mouse 1 or 2.

Could you test with mouse enabled, lightgun disabled, and your mouse, spinner & lightgun plugged in?  And report if works?  Hmm, I could be confusing reload_offscreen option with your problem.  Could you also try the reload_offscreen option on and off, with & without the spinner, please?  Thanks, I hope to find a fix it it's mame. :)
