Mame: game not recognizing keyboard keys when launched from LB

[ksherfinski]

Cab keys that are controlled via an ipac kb controller are not recognized by Centipede, when launching the game through LB.  Other games work as expected.  The start and coin keys are not recognized by a physical keyboard either.

Launching Centipede directly from Mame (same config used in LB) works as expected (arcade cab keys are recognized).  

Funny thing is that Millipede (as well as other games) don't exhibit this behavior and are using the same Mame config as Centipede.

Any ideas?

 

update: (1) physical keyboard works as expected whether going through LB or Mame.

(2) changing "-keyboardprovider dinput" to "-keyboardprovider raw" solves the key issue, but doesn't trigger a "pause", like it does when set to "dinput"

 

I can live without using pause screens for a specific game, but am still interested in a workaround, if anyone has run into this.
