I have never done anything like this before, so please excuse my ignorance if I am doing something that I shouldn't. But there appears to be a bug in Tkinter.py in the delete function in revision r65971, defined starting in line 2660. The line in question is line 2670 and looks like: if (num_index1 is not None) and (num_index2 is not None): This line gets a message in PySolFC like: TypeError: argument of type 'NoneType' is not iterable If have fixed this in my case by adding the phrase "and (self._tclCommands is not None)" to the line. if (num_index1 is not None) and (num_index2 is not None) and (self._tclCommands is not None): John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
