Ah, yes, I had similar problems in GPE. I haven't looked at your code, Simon
(sorry) but in GPE I had dialog boxes with a similar problem. It was even
more noticeable in scratchbox where, after the dialog is dismissed, the
background would reappear and my application window was nowhere to be seen.
On the device, the application window appeared to be visible but clicks were
going to the desktop instead (so, for example, I could invoke a desktop
widget if I touched in the right place)!
In most cases the problem seemed to be that the existing code used the
following sort of construct:
gtk_window_set_transient_for
(GTK_WINDOW (dialog), GTK_WINDOW (gtk_widget_get_toplevel (widget)));
In most cases I replaced that with setting it as transient for my main window
(a HildonStackableWindow). I don't know what the toplevel widget is on
Hildon but whatever it is it doesn't seem to be useful!
In at least one case, the right thing to do was to replace the whole dialog
with a HildonStackableWindow and create a Fremantle-style UI with a stacked
window.
No idea if that will help in your case.
