Alas, what I was referring to was the object graphics
equivalent of TVCRS. This turns out to be an old feature
request that has never been implemented. To work around it,
you usually define some kind of "symbol" object to use as
a cursor, and you move that around in both windows, using
whatever event or message passing capability you have built
into your objects to communicate with one another.

It's a bit more work than I was hoping for, but ... that's
the nature of object graphics. :-)

Cheers,

David
