This is mostly feedback on using Debugger - on DNU, if i press 'create a method' debugger opens, and shows extra (debugger related) context frames up to the method context which is just created. (while writing this, i found that it shows these extra contexts even if i simply press 'debug') : -------------- Process>>suspend OTToolset class>>debug:context:label:contents:fullView: OTToolset class>>debugError: [] in DEVToolSet class>>debugError: {[:obtools | obtools debugError: anError]} [] in DEVToolSet class>>ifOBTools:else: {[:obtools | aBlock value: obtools]} OTToolset class(Object)>>ifNil:ifNotNilDo: DEVToolSet class>>ifOBTools:else: DEVToolSet class>>debugError: ToolSet class>>debugError: UnhandledError>>defaultAction UndefinedObject>>handleSignal: MethodContext(ContextPart)>>handleSignal: MethodContext(ContextPart)>>handleSignal: UnhandledError(Exception)>>signal UnhandledError class>>signalForException: Error>>defaultAction UndefinedObject>>handleSignal: Error(Exception)>>pass [] in PasteUpMorph>>becomeActiveDuring: {[:ex | ActiveWorld := priorWorld.
