Bob, everything seems ok now I have several places where the -min/-max
are changed and I was looking at the wrong one for the tests.

You were right about the vectors and the global scope, This is also
true for BLT so I do not see how my code worked before, very curious.

Now if some kind soul could have a little peek at the update/Configure
problem.

I'm pretty sure that RBC is different from BLT. Since it was supposed
to be a port, and RBC is incompatible, then it is a bug. (Not that I
know how to fix it, yet.)

Or replace those by [tk busy] ?

I suppose that would work for Tk 8.5+ I've lived in 8.4-land for so
long, I forget all the goodies that I'm missing. :-}

In this case, it's part of 8.6.
