Amen.  Double-click is even ergonomically evil and likely to accelerate 
RSI problem.

I find it particularly humous that Doug Clapp is promoting Double-click 
under the banner of "understandability for the average user" as 
double-click is motorically much more challenging that single-click.

The issue of Squeak's dependence on a three button mouse is real though, 
but not a simple problem.  The issue becomes increasingly 
visible/annoying as you go to two button mouse, one button mouse, a pen, 
and finally, keyboard-only. It would be nice, at least for Morphic, to 
be able to handle all these senarios gracefully, but I think this is a 
hard problem.
