That's something I've been considering for a while -- guess I finally have 
the incentive to do it.  Thanks.

PS  I also wanted to tell the list how WELL your pencil-eraser 
keyboard-cleaning process works -- when I first got this puppy, fewer than 
ten keys produced a response;  and alcohol only worked so-so.  But one 
eraser & about 15 minutes, and the flippin' keyboard is like new.
Thanks, and thanks.
