/*NOTE**************************************************************************
This code is maybe the biggest example of a workaround code as it has different
code for all browsers. But it works like a charm :)

Use the style tag to change the placement and width of the layers.
If you are trying to place this into a table cell or something make the
position of the divNewsCont layer relative...Remeber that that might crash
Netscape 4 though, Good luck!
