With most humble apologies to the feline-fem; I did a forum search as well and couldn't raise anything, though I am SURE I remember seeing it discussed. It could have been somewhere else though.....

Actually, there are THREE versions of riddles wisely expounded in the database, and they will come up if you search on RIDDLE....

sometimes I just don't understand computers. But that's what keeps me employed, so I shouldn't complain.
