Edgar, thanks for the picture. It reminded me of a question I've been wanting to ask for while. Does anyone know how revive a morph after an error leaves it with the redbox and yellow x? Last time this happened to me, I couldn't even locate the code responsible for handling this error state and drawing the redbox with yellow x
Look at the senders of #errorOnDraw to find the places that deal with it. The short version is that the system catches errors in drawOn: methods and then walks the stack trying to turn off drawing for the morph in question. You can re-enable drawing by getting the handles on the crossed-out morph, and from the debug halo choose "start drawing again".
