I've never had the demo 3d window close that I
recall. (Maybe it closed on the original X11 only
code). Closing with the mouse does not work
because the demo shuts down the 3D GUI stuff at
the end so there is nothing to twiddle() and
receive the exit window command from the widget.

Right.

I just cut an pasted the example code from the
'help imag2d' documentation and (after a couple
of q's) got 3 windows.
All image windows move and resize and the windows
even close nicely with the system window close
widget.
If I have q'd back to the perldl prompt, they
become unresponsive (since the GUI events are
not being handled). A close window doesn't work....
But if I then run the twiddle() at the perldl
prompt to start the event loop going, the windows
all activate again and any of the previous mouse
events are carried out.
The "b_1: pixel..." started out as debugging messages
and now illustrate the ability to interact with
mouse events programmatically.
You'll also notice that the imag2d() windows are
active when a TriD graphics window is twiddling.
It doesn't work the other way since the TriD
support at the moment is emulating X11 event
processing.
Cheers,
Chris
