        That means that you are setting the Value at the wrong point of the

        This is not the correct call. After I wrote that, I remembered that 
clear() is a paint-related method; the correct call in Dabo is the more 
precisely-named removeAll().

        Try using removeAll() instead. You should not drop into the wx layer 
unless you need to do something very esoteric.
