Hi Scott:
I don't get much out your scroll problem as you mentioned. What I did was
creating a HTML page, in the middle of the page, I embeded a applet. (Yes,
you need to get item.x, and item.y in your Applet's start() method which is
when the document gets visited to pass to the windows etc you need to create
.) What I didn't experienced any scroll related problem is in the init() of
the Applet, I have set the Applet's width and height, and in the start()
method, which I created bunch of windows etc, I used applet's height as the
reference to created base window and its children....and the page behavior
is normal.
