Maybe there is a confusion here. You code above means that, when the event  
"The leftmost MOUSE BUTTON was released" happens over your BUTTON WIDGET  
b, your function will be called.
The "alternative code" suggested is the right way; the "command" is fired  
when the mouse button is pressed inside the widget AND then released  
inside the SAME widget (and the button is not disabled).
