Specifically, if I have a modal dialog which in turn pops up a modal dialog then I find that the second dialog comes up behind the first dialog -- it gets the focus correctly and is indeed modal, but it is concealed by the original window.
Under linux everything works as expected :)
I can get the win32 version to work a little better by setting the original window to be non-modal before popping up the second modal dialog.
See attached pygtk code for a demonstration of the problem.
Is this a bug in the win32 version of gtk or am I doing something wrong?
