[Visualpython-users] Problem with gtk.main()

Hi,

first of all: I just started to use vpython for an existing project and I am
impressed how easy it was to get a good output.

But sadly I encountered a problem, when trying to display the vpython window
along with a pygtk window.
If I just show the vpython window (by commenting out the "gtk.main()" call
for pygtk), everything runs fine. I can rotate and zoom the 3d view with the
mouse.
On the other hand I can disable the vpython initialization and the GTK window
works fine.
But if both are enabled, then the two windows show up as expected, but they
don't get repainted and don't respond to any input. I need to send a kill
signal to cancel the program.

Now I am wondering, if vpython has a problem with a concurrently running GTK
main loop. But I could not find any indications for this in vpython's
documentation or by searching the web.

Does anybody have any ideas about this?

Below you find my currently installed versions of gtk and vpython. I am using
Debian testing.

cheers,
Lars
