//### 5. Detect mouse location and scale clips accordingly###

    } else if (_root._ymouse <%gt%>= (3*(stageHeight/5)) && _root._ymouse <%lt%> (4*(stageHeight/5))) {
        _root.scale  = 0.99;

The rescale() function also has 3 parts. First we detect the location of the mouse in the y-dimension and adjust the value of the variable, scale accordingly. Next we set the values of the Boolean variables, bigger and smaller depending on the current value of the variable, scale. Finally, we check the values of the variables, bigger and smaller. If bigger == true then we first check to make sure that the clip has not been scaled to a size greater than we determined using maxScaleFactor and if this returns true then we scale the holderMovie and the value of the variable clipWidthNow. The advantage to using this methodology is that by scaling the holderMovie clip instance we produce the visual impression that the menuMovie instances have been scaled whereas just the holderMovie clip has been scaled. Because holderMovie is an empty clip, we need to keep track of the size of the clips by scaling the value of the variable, clipWidthNow. The other advantge to using this methodology is that the move() and replace() functions do not have to account for scaling of the menuMovie clips because they are not actually scaled, rather just the clip within which they are nested (holderMovie) is scaled.

I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
