Thanks for the help, Harven. This works.

Is this just a workaround or is this by intent? It seems that for some options
I still need the CONFIGURE function. What is the reason for this
inconsistency? How do I know which options can be set by CONFIGURE and which
need to be set by SETF? I have not noticed such inconsistencies in Perl/Tk
yet. One would use the configure method/function for everything.
