I searched around the forum but didn't see that anyone has had this issue. When I select a game from attract mode by selecting the coin button, it lets me play the game just fine. But now if I try to exit the game by hitting escape it does not let me exit the game. When I hit alt + tab on the keyboard I notice that GameEx does not show up. Only the game that is running in Mame and the GameEx hide OS show up. Now if I end task on the game then GameEx comes back up just fine. Any ideas what could be causing this? Thanks
