IPAC4 winipac reprogramming question - I lost my Exit and Pause keys ?!?

[keno21176]

Hi
I have a mameroom.com quad control panel and I DL'd the Winipac software to reprogram button layout from mameroom's config to mame's standard cfg, but ran into a snag.
I somehow lost the functionality of the Exit (esc) and Pause (P) buttons.  I entered the "key designer" interface to try and re-add the buttons, but I'm unable to map them, it just keeps flashing and does not recognize either key press of exit or pause. (these keys are not activating in emulators, notepad,etc, either, btw but were working fine up till i started messing w/ winipac)  I didnt mess w/ any wiring, so I must've just hosed a setting somewhere but I can't figure out what I messed up. anybody know how to fix this?  I tried to reload the "quad layout" file, but it does not have these buttons.
thanks
Ken
