On RPI 3 with latest version of PiPlay, and IPazzPort Bluetooth keyboard, I have set keyboard mapping in advmame.rc to recognize keyboard inputs and all works great in both AdvMame and Mame4all. Likewise, the PiPlay main menus work perfectly. My problem doesn't present itself until I press TAB and bring up a "Popup" menu from within AdvMame. The popup is displayed, however, I can find no input that will allow me to scroll to select anything from the menu. The Up, Down, Left, Right keys seem to work perfectly in every other case just not within the "Popup" menus. I must be looking right past the issue, and any thoughts would be greatly appreciated.
