Several users have reported being unable to use buttons mapped as triggers on joysticks, mainly using the XBox 360 driver. The buttons register correctly in the diagnostic panel, and work properly in other emulators such as the latest MacMAME, but cannot be mapped from the Tab menu. These buttons are not actual triggers, but digital buttons corresponding to those inputs. Tested hardware was the Hori Real Arcade Pro on Macbook with driver from Tattiebogle.net. User on Shoryuken.com reported same issue with Mad Catz Tournament Edition stick.
