I'll follow up logged an issue soon, but just a quick note while I'm in the flow on something else...
1. Pick an existing test method e.g. AST-Tests-Core > NumberParserTest > testFail 2. Insert an error like 1/0. 3. Run test from System Browser by clicking on the method's circular icon 4. Click on top of stack "SmallInteger /" --> MessageNotUnderstood: receiver of "paneNamed:" is nil At step 3, instead clicking <Debug> works okay. cheers -ben
