Solved! (For Realz this time). After BOP crashed just now I realized there was some documentation in there that outlined what the script that keeps crashing actually does. *DOF method for rom controller tables by Arngrim********************'*************************use Tabletype rom or em********************'*******Use DOF 1**, 1 to activate a ledwiz output*******************'*******Use DOF 1**, 0 to deactivate a ledwiz output*****************'*******Use DOF 1**, 2 to pulse a ledwiz output**********************Sub DOF(dofevent, dofstate) If cController=3 ThenIf dofstate = 2 ThenController.B2SSetData dofevent, 1:Controller.B2SSetData dofevent, 0ElseController.B2SSetData dofevent, dofstateEnd IfEnd IfSomething about this reminded me of the PinballX LED Plugin works so I disabled the LED Plugin and Voila! Problem solved. I liked the way I had the LED Plugin working so I will go back in later and see if maybe it was just an issue with how I configured it but at least I know what I'm dealing with going forward. As a bonus, I had implemented a few performance tweaks when I was stuck in DB2S standard mode and they didn't do enough to make me happy then but now that I am back in EXE mode things are the best they've ever been performance-wise. Good-Night!
