change the first two lines of that onLoad statement to store your movieclip's
initial _x and _y properties.  (the first two lines currently do nothing.)

and use an else branch of your if-statement to update that movieclip's _x,_y
properties using those initial properties instead of endX and endY.

That makes sense and works...but the issue is now this other tween that you
helped me with, that makes the MC hover.

This is the code that makes them hover.

I think it's the code that tells this hovering tween to 'start tween' that is
causing the MC to jump.

Here is the fla so you know what I'm talking about.

thanks.

you many not want to resume those tweens onRollOut then.  if you want to start
a new tween onRollOut (using the possibly new _x and _y properties of your
buttons), then change the current rollOut handlers to do just that.

kglad,

That seems to make sense, to start a new tween on roll out based on the
current x and y position of the mc.  That way, it wouldn't 'jump' but would
instead go smoothly into the hovering.

But, how would I start a new tween on roll out? The code would have to be the
same as the previous 'hovering' function you made, right?  But I would have to
give it a new name?

Then, if you roll over the mc again, wouldn't it only stop the first Tween
instance?

How would I make it stop the second one?

Thanks

kglad,  amazing, it works. Thanks so much, you are a stud.

Do you have a personal site?  I have tons of flash work and would like to know what you're up to, to perhaps call upon from time to time.
