Hey all,
  Okay, just finished re-loading the Aces High associated CH File.  It appears that when I manually turn off DX mode for each key another key on the MFP becomes available.  I vaguely remember reading about a limit of 32 DX Mode Keys somewhere and (obviously with a stick, throttle, pedals and an MFP (w/25 keys)) I maxed out the DX mode capability.
  While I will need to script in each of the MFP keys now, I should be able to get them to work.  I do have a couple of keys that are non-responsive, but hey, the board has been around a while and I may need to re-seat them.
  Thanks all for the help.
Regards,
