Hi Folks -

I'm seeing a seg fault when I try to use a gui written in Python,
launching it via pyexeci in te global section of my orch. My shell
output, csd, and py source are pasted below.

I launch the .py containing a simple gui with the pyexeci opcode (see
below).  The catch (possibly) is that I'm using pyFltk, a python
wrapper for fltk.

I've got FLTK 1.1.7 on my machine, which is running Winxp pro on an
2GHz Intel Pentium M.

One assumption I have, is I should be able to access the global vars
here via pyassign.  True?  If anyone can straighten me out as to what
I'm doing wrong, I'd appreciate it.

Thanks so much - Ben
