[squeak-dev] OpenGL morphic issue with "embedd in window"

Jeroen has been helping me more than a bit with learning how to use
OpenGL with squeak, but I've hit a stumbling block I can't quite get
around and Jereon has been busy lately:
when I put an OGLMoprh in a window via the menu, the close box
apparently doesn't delete the morph the same way as it does via using
the x-halo (without embedding)
The x-halo sends a delete directly to the OGLMorph which sends
OpenGL>>destroy.
However, the window's close box AND the window's x-halo apparently do
things a tiny bit differently.
The window disappears, and the OpenGL context becomes unselectable, but
stays around.
If I send openInWorld to the original OGLMorph, it becomes active again
and the x-halo of OGLMorph will still do the OpenGL>>destroy on the
context.
I've tried to trace what is happining, but I am missing something. The
messages I expect to be called are not being called, so I can't figure
out where to put the reference to OpenGL>>destroy to tidy things up.
The procedure for installing OpenGL class in squeak 4.1 is:
(Installer repository: 'http://source.squeak.org/FFI')
install: 'FFI-Pools';
install: 'FFI-Kernel';
install: 'FFI-Tests'.
(Installer repository: 'http://www.squeaksource.com/CroquetGL')
install: '3DTransform';
install: 'OpenGL-Pools';
install: 'OpenGL-Core'.
and then install thelatest OpenGL-Tutorial package via monticello from
'http://croquet-src-01.oit.duke.edu:8886/Contributions'
myMorph := OGLMorph new openInWorld.
menu>> Put in window
will show the behavior I'm talking about.
Thanks for any advice.
