Jim,

Actually, I didn't know all that, I'm glad you wrote it :)

What if you don't want native widgets, but you do want native windows 
and window frames? I believe users will be thrown a little bit by having 
a bunch of entities that look just like application windows, but 
actually are not ("why can't I minimize it to the application dock, why 
can't I alt-tab to it?"). However, I *don't* believe users will be 
thrown by widgets like buttons or comboboxes that look just like OS 
ones, but actually are not.

Are callbacks required, say, for implementing a modeless child window as 
an OS window containing a Morphic world?

In otherwords, is the problem simplified if the only callbacks you need 
are for a couple of special cases, such as resizing of windows, rather 
than a generalized callback implementation?
