Maybe I just have a double-clicking brain! Nothing to do about that, although I'd love to have the brain I used to have in the 70's...would need all I've learned since then transferred over to the new, better brain.
Maybe the computer I'm using, which I'll get rid of as soon as I can get someone to set up my new one. Or my mouse, which is pretty old...not as old as I am, however. Will have a new mouse when the new computer is set up.
