I have seen
this effect used to good effect a few times and couldn’t find a good tutorial
on how to achieve it. So here goes… my first tutorial!
It is not possible to drag a mask in Flash 5 so instead
we simulate it by creating a mask that moves normally and then set up some code
to check the mouse position and make the movie move to a certain frame number in
the movie depending on that mouse position. It’s easy once you know how!!!
