[Newbies] Catching message send

One common, if unartful, technique for doing this kind of thing while  
debugging is temporarily to stash a reference to the specific object  
in a global, and then, in the method in question, check to see if the  
receiver is that object.

Thus, in an Inspector on the object in question, evaluate, say,  
"Smalltalk at: #AA put: self".

Then in the method in question, put something like  "self == AA  
ifTrue: [self halt]"

To clean up afterwards, you can evaluate "Smalltalk removeKey: #AA  
ifAbsent: []" and, of course remove the debugging code from the method.
