Anthony,


> Does it work if you proceed?

If you hit proceed, it brings up another DNU. If you debug, the debugger
isn't very happy. If you click on a member of the upper pane list in the
debugger, you get another 'proceed for truth', and eventually some very nice
transparent DNU ones also, so you're pretty much dead in the water for
debugging purposes.

The debugger call statck (watch out for types, I had to hand transcribe it):

NonBooleanReceiver(Exception)>>signal
NonBooleanReceiver(Exception)>>signal:
SmallInteger(Object)>>mustBeBoolean
Parser2>>expression
Parser2>>statements:innerBlock:

Hope this helps,
