I have a Flash file that is 1044 x 2560 that is embedded in an HTML doc. The Flash file contains a MOUSE_DOWN function that triggers an ExteranlInterface.call which triggers a JavaScript function in the <head> section of the HTML doc. This JavaScript function needs to somehow cause the vertically scrollable area of the HTML doc to re-size from 1044 x 2560 to 1044 x 1800. Is there any way to force this change in height?

Thank you in advance for any advice.
