Thanks John.  That fixed the hanging process.

Now a message is coming back "none active" from the
function:

    def _get_active(self):
        if len(GcfBase._activeQue)==0:
            print 'None active'
            return None
        else: return self._activeQue[-1]

in the _matlab_helpers.py file.  

I haven't traced it back further yet.

Cheers.
Barry
