Ah, thanks.
one issue I see the Qt.Tool flag is that it won't close the widget when
I click outside of it, something the Qt.Popup flag does for me.
But I guess I can re-implement one of the event handles to reproduce
this behaviour. MIght be easier than hunting down whatever would
suppress the shadow in the default palette.
Cheers,
frank
