Seeing as how my SetMouse() routine is being bandied about, with people 
screaming that mouse moving is the devil's work, I thought I'd post a rebuttal. 

This a very simple demo of a reason to move the mouse under program
control. It illustrates a control, called a "Numerical", that I first saw
it in a program by David Zicarelli. It appears in many music programs
(Opcode, Intelligent Music). I wanted to use it, so I cloned it. It gives
the feeling of directly manipulating a number. In a real program the user
would be able to type into it, too.

There are other good examples of moving the mouse, like pop-up palettes
that put the mouse on the current selection. Even Apple's pop-up menus
should move the mouse when a menu is close to the top or bottom of a
screen, and not moving it would result in the mouse being over a scroll
area. The idea of "warping" a palette to the current mouse position (which
I don't like any better than forcing the mouse to the palette) only works
if the edge of the screen doesn't get in the way. Games like Solarian II and
Crystal Quest are good examples of low level mouse control.

To sum up, I think that there are cases where moving the mouse under
program control is a good thing, not for the elusive "ease of use", but
rather, to create controls that couldn't exist otherwise.
