Tina,
You don't want to create a new thread -- Tcl/tk can only support
a single thread. Instead, you either need to wholly replace the
external GUI with your GUI, or you simply need to make your gui work
with the standard external GUI. The latter is generally done by adding
your own menu, which then creates it's own window in response to user
requests.
Cheers,
Warren
