I hit some strange behaviour... Setup... 1. In playground, type... green 2. Open implementers on it 3. Select the second line "Color class(defaults) green" 4. Click in the code pane Observe that "green" is pre-selected and the cursor is flashing at end of first line 5. Start typing... self halt. Observe the method name is overwritten
Problem... 6. Hit CTRL-Z three times. Observe the instance side #green is displayed rather than the class side. Auxiliary... Now save it and work out how to get out of the mess (pretending you didn't notice what had happened) https://pharo.fogbugz.com/f/cases/19972/Implementers-code-pane-undo-goes-too-far cheers -ben
