problem extending tkSimpleDialog.Dialog

[William Gill]

Problem solved.  I was not properly passing the master widget reference 
in my frame classes

class MyWidget(Frame):
     def __init__(self, master, columns,rows, trace_write=None):
         Frame.__init__(self) #<<<< here's my mistake
     ...
     ...
     ...

should have been:

class MyWidget(Frame):
     def __init__(self, master, columns,rows, trace_write=None):
         Frame.__init__(self,master)
     ...
     ...
     ...

P.S.  I haven't been working on this since my last post.  I had to quit 
to go see my oldest graduate.
