[PySide] how to suppress qwidget's drop shadow under windows?

[Frank Rueter | OHUfx]

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
