Use the mouseStillDown message, which is custom configurable based on 
the idleRate and idleTicks properties.

Something like:

on mouseDown
   scrollTheField
end mouseDown

on mouseStillDown
   scrollTheField
end mouseStillDown

The problem isn't the use of the mouse function, or the mouseLoc 
function; it's with this:

repeat while the mouse is "down"

Just querying the mouse in a handler that is calling itself (by using 
send in) every few ticks is fine. Using repeat while the mouse... leads 
to hogging system resources unnecessarily and possibly wrong results.

I hope this helps. Feel free to contact me if you have any further 
questions.
