It's the way you are pushing down the .content divs.
Those two divs must appear low enough to make room for
the absolute header. They can be relatively offset, as
you have them doing, but when they do, they do it as
rigid boxes. (in this case, both boxes behave the same
as a single box would)
So when they are dropped, the bottom part of the second
div extends beyond the bottom of the body element, and so
can't be seen. Op6 is nice enough to also extend the body
far enough to accomodate it, but Moz and IE do not.
The fix is not to use relative offset to lower those divs,
but instead use a margin. A top margin on the body will
reliably do this. Top margins on the children of body
don't always work correctly (at the top of 'body').
