I did go ahead and make a bunch of button handlers. Start, pause, load, etc..., using print to verify. I haven't associated an actual function/action to them, but I did notice that ifI were to press the "X" in the top right of the menu, near the minimize, maximize buttons, I do get another error. Can that be controled/associated with a created button like Quit or End script?
The error message says: lua:381: ERR_INVALIDOBJECT
I think it would be smart to associate that to a created 'quit script' button by the user and if possible, disable closing that ability if a button didn't exist. Or is that something inside of OEUO that Cheffe will eventually have to address?
