Thanks, all those suggestions worked.

Well, I am constrained to use clisp or sbcl.  I plan on getting around
the callback issue by running the gui in a separtate .NET thread and
running and event loop on the lisp side to listen to .NET events over a
set of synchronized channels.

Btw, it needs a little cleanup, but I've updated the VS 2005 version of
the cpp project to conform to the 0.6.0 protocol.  Would you like a copy
of it when I have it ready?
