gnet's callback should not be called on any gtk events. (No one except
gnet should be posting to gnet_hWnd.) If this is happening, it could be a
bug in gtk or glib. Could you send me a sample program that shows this
problem? I won't be able to investigate until late next week at the
earliest.

That is odd. I will look into that. Do you have a sample program that
your can send me?
