Ignore my last email, John. I managed to find a non-gtkmm window where I was able to reproduce the problem - so it's definitely a GTK+ issue, like you said. I came across this entry in bugzilla:-
https://bugzilla.gnome.org/show_bug.cgi?id=646930 which is the same problem AFAICT. This seems like a good place to start looking for the fix. Frustratingly, it looks like it got fixed only a couple of months after we installed GTK+!! Thanks for your earlier help and for letting me have that sample app to try.
