Not a problem.  My biggest problem is that I do king safety in two places,
one for the real scoring, the other for handling the castling issue.  And I
often change the first one, and totally forget about the last place.  And
the castling stuff then goes bananas...

I usually try to check this out, but I certainly had it in an early 17.x
version.  I don't think I do now, but won't make any proclamation to that
effect until I have looked at the code carefully.  :)
