I would strongly support this, particularly for the last reason. I have seen 
people double click on things and cause all sorts of problems in single 
click mode. For example, double-clicking a document on many systems will try 
to double-start OpenOffice, leaving the system crying on the floor.

However, I do have a question. I don't use single-click mode, so I wouldn't 
know, but is there any instance where, in a mostly single-click environment, 
double-clicking has any use?
