Hey!

I just realized that alt-. doesn't seem to fly on my Ubuntu 12.10 in Pharo 1.4 nor 2.0 one-clicks.

It *does* however work fine in Squeak 4.3 one-click.

In Squeak I can: Run "(Delay forSeconds: 5) wait" and interrupt it with alt-. Or just press Alt-. and get a debugger.

Also it seems that Process browser in Squeak is opened up *without* having any process be suspended. Not sure why Pharo is different there and shows the UI process as suspended?

regards, G?ran

I do not know if this is relevant to Pharo any more, but there is quite of bit of information about problems of this type in the links starting at http://bugs.squeak.org/view.php?id=7655. Maybe this will give some ideas for debugging. The four test expressions that should be interruptable (per Andreas Raab) are: [true] whileTrue [[true] whileTrue] forkAt: Processor userSchedulingPriority + 1 Smalltalk createStackOverflow [Smalltalk createStackOverflow] forkAt: Processor userSchedulingPriority + 1 Extra credit if anyone can figure out how to turn those expressions into unit tests ;-) HTH, Dave
