[font=Times New Roman][size=3]Please can anyone with advanced knowledge of Actionscript please help me with my code (shown below) in respect to a requirement for zooming?[/size][/font]

```
 [font=Times New Roman][size=3]I'm creating a flash animation in which I'd like to 'zoom' in and out of a movie clip when the mouse is held. I only want to zoom into the movieclip if the mouse is being held down and if released the movie should zoom back out. [/size][/font]

 [font=Times New Roman][size=3]I'm using someone else's code (shown below) which gives me the ability to zoom into a point where the cursor is clicked. If the mouse is clicked a second time it returns back to original resolution. The code uses onClipEvent (mouseDown) rather than this.hitTest to ensure the zoom goes to the area the cursor is positioned.[/size][/font]

 [font=Times New Roman][size=3]Is it possible to adapt this code so rather than just zooming to a set magnification and stopping, it zooms only if the mouse is held down, and returns to original resolution on the mouse is released?[/size][/font]

 [font=Times New Roman][size=3]The .fla for the code I am using is at:[/size][/font]
