That is beside the point.  As accurate as "richard"'s problem descriptions 
usually go, chances are it did not say that their "mouse had been idle", but 
that *they* had been idle, i.e. they had not navigated anywhere on that 
site.  You can deal with this condition with a META-refresh, although as I 
said it is not reliable.

There is no "javascript".  In any ECMAScript implementation, it cannot be 
done reliably either, partially because one usually cannot determine pointer 
movements beyond the browser viewport.
