I've mapped 2 buttons on my control panel using winIPAC to VOL up and down. Works perfect in windows explorer. I've also mapped the buttons to VOL up and down in BigBox. When I hit either volume button BigBox freezes and continues to apply whichever volume button I hit for 30 seconds, then it proceeds to raise and lower the volume while not allowing me to do anything other than ctrl+alt+del. Everything else works great, but the volume control in BigBox is the last piece of the puzzle before actually start to build the arcade cab.
