Is there a way to debug or even put Transcript writes into event handlers like drawOn and extent. My attempts seem to hang Squeak.
Thanks

Look at my CircularTranscript package (should be on SqueakMap but I don't seem to have put it there); it is a transcript that you can write to during event handlers, as it doesn't cause an immediate redraw.

You can't usefully use an interactive debugger from an event handler.
Thanks,

Here is a example I just did in FishEyeMorph that worked
extent: aPoint "Round to a number divisible by grid. Note that the superclass has its own implementation." | g gridSize | gridSize _ self gridSizeFor: aPoint. "self halt." Transcript show: aPoint asString. g _ (aPoint - (2 * borderWidth)) // gridSize. srcExtent _ g * gridSize. gridNum _ g. ^super extent: self defaultExtent
