Great- although I have to say "Are you sure?" dialogs are an evil that
should be avoided - they drive me mad! (the Undo is sufficient!)

Mea culpa - that worked beautifully. However, it didn't work all that
well at the start of my model building, presumably because the sequence
identity between molecules was low (lots of polyalanine)....
