well, I got a new mouse today. It is an optical mouse. It seems to be somewhat lighter and a little finicky. Sometimes it just bounces off the screen as though it tripped and fell. Perhaps it is not an optical mouse at all, but a blind mouse. Perhaps I require three of them as in three blind mice to properly execute any mouse procedures. Maybe I should have ordered a tail less mouse. As in, cut off their tails with a carving knife, three blind mice. Do you suppose they are now employed by Microsoft? Oh well, I am sure I will develop some level of expertise with my new mouse at some point.
