Another effect I have noticed that has not been mentioned here, is that if 
there is a focus shift required, that focus shift gobbles up the first 
click.  IMO it should pass the click on thru AFTER effecting the focus 
switch.  But my opinion and $1.34 will get you a 16 oz coffee to go at 
7-11. :)
