Are you talking about a tenth of a pixel?  I can't understand why you're

trying to move something *slowly* over a 1 or 2 or 3-pixel distance in

the first place--how could Flash move something less than one pixel at a

time and how would you tell if it's moving quickly or slowly over such a

small distance?  The only suggestion I can offer, since I don't quite

get what you're trying to do, is to start with bigger numbers--ie,

multiply your initial start and stop numbers by something like 100 or

1000 before you divide (and then set them back before you do the move),

so you're not doing operations that depend on ever-more-exact decimal

precision, which maybe Flash's floating point operations are not set up

to handle.
