I recently recieved the X-Arcade Tankstick with the trackball. The unit is great. However, the trackball is working very strangely within GameEx. Mame32 is set to use mouse as input, the in-game settings are set correctly to use mouse. The trackball moves the cursor in Windows, Media Center and GameEx. I spents hours trying to get the trackball Mame games to work with the trackball. Finally they started working (I don't know what, if anything, I did to make it work). Then I unplugged the X-Arcade unit. After re-plugging it in, the trackball games stopped working again (the movement is controlled by the joystick). I am baffelled. Why did they trackball games finally start working. And why did they stop when I reconnected the unit??? I don't know if this is an X-Arace, GameEx, or Mame issue! Any help would be greatly appreciated. Once other note: When the times when the trackball is not working correctly, Windows Media Player keeps launching. I assume this is some kind of hot-key combo, but I don't know where, or why it seems to be related to the trackball. Any ideas? Many, many thanks!
