Off-hand, you can set the sensitivity of the mouse on both Mac and Windows
platforms. But you are going to find that some makes of mouse behave a
little differently: some come with acceleration features, or other custom
drivers, for example. I guess you would need to ensure, make model and
settings are the same, unless you can come up with some other way of
compensating for this.
In MetaCard, you wouldn't use "idle" to track mouse movements (idle is
obsolete and included for backwards compatibility only). See the article on
"send vs. idle" on our web site. For mouse movement it gets even easier,
there is a mouseMove message that gets sent when the mouse is moved, e.g:
on mouseMove x,y
put x,y
end mouseMove

Probably does make the grey more present - try turning it off (set the
backColor of stack "myStackName" to white) or printing full size to see if
that makes a difference.
