Hi Nicolai, I had a bunch of messagebrowsers open, mostly on various classes of Morphic and Montecello packages; nothing that was related to the class I renamed. Since I got your message I have closed the MessageBrowsers, and now there are only two debuggers triggered when I add or remove a method :-)
It looks like WorldState's queue of deferredUIMessages contains a stale block or something... runStepMethodsIn: aWorld "Perform periodic activity inbetween event cycles" | queue nextInQueue| "If available dispatch some deferred UI Message" queue := self class deferredUIMessages. [(nextInQueue := queue nextOrNil) isNil] whileFalse: [ nextInQueue value <----- error ]. self runLocalStepMethodsIn: aWorld. "The multi-threaded global Transcript needs to be updated periodically and synchronously with the UI." Transcript stepGlobal.
