No scrolling in Netscape 4.x
The AutoScroller won't scroll in Netscape 4.x
By default, the AutoScroller defines the styles for the content layer embedded in the <head> section of the page, but chances are you've somehow altered those styles and now all or some of the styles for the nested layer are directly on the layer itself.
However, Netscape 4.x chokes on styles defined directly on nested layers and will refuse scrolling.
To fix this, you can run Yaromat's "Layer2Style" extension (available from http://www.yaromat.com/dw/index.php?t=Command&r=layers), or move these styles manually to the <head> section of your page.
