Anyone know if the following bug has been logged previously? I've had a quick search and not found anything. 1. #hierarchyButtonAction: inspect 2. Select [Implementors] tab. 3. Select [Source tab] 4. Edit method, the yellow dirty mark shows in the corner 5. Accept edit e.g. <Ctrl-S> ==> nothing seems to happen. The method still shows dirty, ==> but if you select [Senders] tab and back to [Source] tab ==> you see the method *was* saved. cheers -ben P.S. Its really cool to be able to edit the method here. I'm using halos to dive into a PluggableToggleButtonMorph (e.g. <Hier>) then selecting the actionSelector > Implementors > Source and insert a halt.
