Works like a charm, David, thanks! I'll have to reread your book
again. I should have caught onto the tlb keyword....

You could use the TLB keyword to get back the identifier of
the top-level base widget used to create the "window". But
you will have to remove the BLOCK keyword to get this to
work. After you have written your image, just call
Widget_Control, tlb, /Destroy to destroy XObjView. Note
that the object hierarchy you passed to XObjView is *not*
destroyed when XObjView is destroyed. So you will have
to do that separately.
Cheers,
David
