I wondered if that mightn't be the case.  That's fortunate.

Actually, I didn't particularly want rounded corners, although I'm not 
sure I care that much.

If I set fusion for the whole app [app.setStyle('Fusion')], I don't get 
rounded corners by default.  But if I apply the proxy style, then I do.
If I don't set fusion for the whole app, I get rounded corners either 
way.

And here's another interesting factoid:  It seems that just the act of 
trying to create a proxy style based on the existing style causes a 
crash.  This statement:

     self.style = Style(file_menu.style())

makes the app crash on exit, even if I never actually use the created 
proxy style.

Anyway, thanks again for your help.  All this gives me plenty to go 
forward with.
