	This is a cunning hack around having to create a new IDL interface
it seems :-) Just a minor point; the properties are CORBA_any *'s at root,
and you should be able to pass a CORBA_any with an object in it; this
would be considerably simpler and quicker than stringifying and parsing
the IOR again.

	Wierd; are you sure you are sending a different control object
reference ? it is certainly not possible for a single control to be inside
two ControlFrame's, if you try and do that you might get this problem.

	Hmm; it is always good to split your apps into lots of
components; however with scolling and controls, it is almost always best
to let the control manage the scrolling, and to insert any UI items needed
to control this into the container.

	Well it's not so pretty :-) but it should work AFAICS, is it
possible you forgot to do a 'show' on the widget before putting it in the
2nd control ? show_all will not propagate over an X plug / socket.

	Regards,
