Just a side note to what a 200 year old would think---I recently asked my 98 year Mother what she thought of all the changes from her childhood to now........her reply I"m to busy learning what a "mouse" is to think about it and by the way how do you keep that thing on the computer screen from jumping around? So I guess I will have to wait a few more years for an in depth conversation of the past. Thnaks Pat
