This looks similar to the problem that I reported earlier with running
multiple Tk's.  The original post is here:

I dont know of a fix and am not sure David has one.  One way out of
the problem is to not call Tkinter.Tk() several times and only call it
once (or atmost twice) for the application.  I am not sure what
Tkinter.Tk() translates to in Tcl though.
