What steps will reproduce the problem?
1. start of the windows ccl IDE
2.  load xmlisp-init
3. Execute this code:
(in-package :xlui)
(setq window

<agent-3d-view>
<cube/>
</agent-3d-view>
</application-window>)
3.  Select the cube that shows up (notice the cube is highlighted)

I expect that this will not crash the IDE.

This bug is easily reproducible on two mac computer running windows XP and 
windows 7 on 
parallels, and on normal PC running XP and windows 7 but it seems that Gary has 
not been able 
to reproduce this bug on his machine.

Fixed by r377.

This was your bug (i.e., in XMLisp).  The size of the buffer passed to 
glSelectBuffer is the number of GLuint's that 
can be stored in the buffer.  So, you need to allocate a buffer large enough 
and your code wasn't.  (It allocated 
BUFSIZE bytes and told OpenGL the buffer was BUFSIZE GLuint's.)  Consequently, 
you were experiencing heap 
corruption which eventually lead to the behavior you saw.
