Hi Laszlo,
It's difficult to help without a complete working example. But I have a few
suggestions.
1) Why not call self.parent.Close()? It seems a bit more polite than .Destroy().
2) I saw this in the documentation for Destroy() -- "Frames and dialogs are not
destroyed immediately when this function is called -- they are added to a list
of windows to be deleted on idle time, when all the window's events have been
processed." That might be consistent with what you're seeing. The window you're
trying to destroy has no events in its queue. WHen you move the mouse over it,
the window processes those mouse events and then wx realizes, "Hey, this window
has processed all of its events, and it's on the list of windows to be
destroyed. I'd better get rid of it."
If you're interested in experimenting, find a non-mouse way to force that
window to process an event and I'll bet that would have the same effect as
moving the mouse over it.
3) Both the wxPython and wxWidgets mailing lists are probably better places to
ask for help on wxPython.
Good luck
