specific zooming

[tomatie]

We are laying out HUGE maps in the background - viewable through a transparent window. We are trying to zoom in on these maps with a blip to show where they must go - we can get it to zoom but not so that the x, y coordinates that we clicked on are still in the centre of the screen with the blip still on the right spot? What actionscript or function would do this - with out putting the blip back AFTER resizing... it must stay visible??
