When I open a table in Pinball X, the DMD will appear for a moment, and then vanish. When I check in Regedit the VPinmame settings, the X coordinate of the DMD has jumped 4000 pixels. If I reset the coordinates to what is in the default configuration, the table will work in Visual Pinball but once opened again is Pinball X, it will do this again. How can I fix this?
