When you press it when idle? There needs to be something to be  
interrupted...

Hi - on a fresh Pharo 2.0 image (build 20041) open Nautilius and press  
cmd-dot: the usual User Interrupt debugger will appear.

Close the debugger and click one of the Nautilius packages and press  
cmd-dot: nothing happens.

Open a new Change Sorter window, go back to the previous Nautilius browser  
and cmd-dot works again.

This is on Mac running OSX 10.6.8.

- Francisco

Indeed. I could reproduce the problem. If you do cmd.-  in the desktop it  
works. If you select a package in Nautilus and there you press cmd.-  it is  
ignored, nothing happpens. Looks there is a problem with Nautilus of  
KeyMappings.

key not working
http://code.google.com/p/pharo/issues/detail?id=5766

Hmm, don't think so :).

The event reaches the user interrupt handler
I've put a transcript log in

UserInterruptHandler>>handleUserInterrupt
        "This will be called from the event-fetcher process.
        Assume no system-vital processes have a lower priority than this, and are  
thus ok to interrupt"
        UserInterruptHandler cmdDotEnabled
                ifTrue: [
                        [ |toInterrupt|
                        toInterrupt := self processToInterrupt.
                        Transcript show: toInterrupt asString...
                        toInterrupt ifNotNil: [
                                toInterrupt debugWithTitle: 'User Interrupt' ]
                       
                        "fork exceptions, we don't want interrupt handler to die"
                        ] on: Error fork: [:ex | ex pass].
                ]

prints nil.


Even more:

(Processor  instVarNamed: 'quiescentProcessLists')
        reduce: [ :a :b | a union: b ]

yields an array with the idle process only.  Which is not interrupted.  
Don't know why the UIProcess is not in the process lists of the Processor.

Yes we were puzzled with igor this afternoon. We should check that because  
this is really strange and crucial :)

http://code.google.com/p/pharo/issues/detail?id=5766

We check with igor and the interrupt key is working. The point is that the  
interrupt key interrupts perfectly endless loop but if you just have a  
plain normal world, the UI process is periodically suspended and the  
interrupt handler is not looking at suspended process (because they are not  
creating loops). Igor will correct me because my vocabulary is probably  
incorrect.
