 I don't know why a COM object would behave like this.  That's unusual. 
As an experiment, you could try deleting the object to see if that's
enough to let the other apps run:
    del beWise

However, since you have other object instances hanging around (the
varInt and varString), I'm dubious that it will make much difference.
