Hi Greg,
a couple of questions first.

What problem is caused by having the Popup menu use a parent?

Have you tried using a non-visible parent?

Now, the reason you need a parent is that win32lib calls the API routine 
"TrackPopupMenu" to manage it. And this routine needs a handle to a window 
so that messages can be passed to something. Your application needs to 
receive WM_NOTIFY etc messages to know which menu item has been clicked.
