ok- this is soo frustrating. Everything's been working fine w/ buttons. Now, all of a sudden, my Player 2 button is firing BOTH the P1/P2 button 1!  So, when I just play P1 and hit the 1st button, it works great. I play the P2 hit the 1st button, it ALSO fires P1 as well!  I checked the input settings- and neither are mapped to the same letter (I think P1 is set to Left control or J1 Button 1 or Mouse 1 button 0- or something like that, and P2 is set to the letter A).   So I delted the ENTIRE cfg folder out, and restarted Mame Analog+.  Same problem occurs. 
Does this have anything to do with the siwtchable mice setting I changed earlier in order for me to get to TBs at the same time?
Thanks
