Al,

This deadlocks the UI for me (Mac/cocoa 64-bit). In the past I've noticed slightly different behavior in SWT between Mac carbon and Linux. On one (can't remember which), setting a text field/combo value programmatically will trigger a modify event and on the other it won't. It may be that there is a similar difference between carbon and cocoa, or it is something else similar to this.

BTW, I notice that you're using capitals for button and heading text. This is contrary to the Eclipse guidelines (http://wiki.eclipse.org/User_Interface_Guidelines). Please follow the guidelines as closely as possible.

Cheers,
Greg

That is why I was wondering if there exists a sane install of 32-bit cocoa (in which case it is just the peculiarities of my machine), or whether there is some fundamental incompatibility between my code and the cocoa windowing system (I don't see how, though, since I have not written anything platform specific into this code).

Debugging this, it seems that the listener calls the correct code I've implemented, and the method exits.  But something at the event layer seems to be causing problems.  I am running M7 still; do you think this could be an incompatibility with anything that is currently in HEAD (I myself would doubt it).  As I said, I have not touched the code since I checked it in, and when I checked it in I had never noticed this behavior before.
