Working on a complete cab with flight sticks, rotary knobs, trackball, etc. Got my new IPAC hooked up and told GameEX to use IPAC support. All the buttons on the machine test fine and even the keyboard tests fine through the IPAC software. But when I launch GameEX or even MAME, I cant exit or "Back" out of a game after being selected. Doesn't work on keyboard or the cabinet buttons. HELP! Am I doing something wrong. I am not using a Slickstick but am using a Gameport adapter to USB for the flightstick I got from HAPP. Any ideas? Thanks.
