I suppose it's theoretically possible, but there's no native support for it.
What you'd need to do, I think, is set up a hidden form with a Timer on it,
and re-set the timer whenever the user does something. There'd be an
overhead hit, but probably not a huge one. There would be a huge coding
hit -- you'd have to add that "re-set the timer" code to every form and
report.
