I just added 2 more buttons to my 2 player cab. It had 5 per player before, so now it's 6. The 2 that I just added are both NEW Happ/microswitch. I open WinIpac and push the buttons, all previous ones work, but when I go to layout designer, add the 6th button to each player and then try to program it to a key, NOTHING HAPPENS! I checked continuity between the grounds and the wire going to the IPAC4 and all is good, so I know it's wired properly and grounded properly. I've switched wires from working buttons and they work. I just can't add NEW ones. The new buttons are going to P1SW6 and P2SW6.
Upon startup of the PC, the IPAC4 LED does not blink to indicate a problem, it instantly goes green.
Does anyone know what could be wrong?
