I am playing Grandma tech support again this weekend, and a thought occured to me. She uses an HP desktop with Windows XP (we needed a cheap-o desktop for her to play solitaire and mah-jong on, and she was already used to Windows ME.) A good chunk of her issues seem to come from the right click on her mouse. Could I buy a usb one-button mac mouse and use it on her computer? No one but me ever touches it for any tech reasons so I could always plug in a regular mouse for those times. But she's 90, and her mousing skills are awful, and she keeps generating extra icons of everything through careless right click, create shortcut. And god knows what else she's accidentally done. The single mouse button seems like a quick and dirty solution but would it work?
