Arghhh. Thanks for the tip. It all makes sense now and indeed, the segmentation faults disappear when following your suggested strategy of avoiding destroys.

I note that if you ever destroy a TopLevel window, you eventually provoke another segmentation fault. However if you withdraw the TopLevel windows instead of destroying them, you can go on seemingly indefinitely by withdrawing the old TopLevel window and then defining a subsequent TopLevel window.

Then to exit the MainLoop gracefully, you destroy the original (hidden and withdrawn) MainWindow.

Thanks,
Stefan
