python/wxPython opengl question

[alan scales]

i have a python app (using wxPython).  from it i create a top level
window (frame) using python opengl. this works:  i have my app
running, and alongside it the gl graphics window.

however, when i close the opengl window, it closes my wxPython app
(and the python console) - i.e. everything.

i don't want this behavior.  is there any way to prevent it?  

for the gl window i am just making a standard
glutCreateWindow(title)call.
