Problem with <DIV>'s with IE 5.0 (but not IE 5.5)

[Brent Bigler]

Take a look at this page: http://bigler.info/v3/photos.aspx

It's supposed to have a header menu ("Planet Brent"), and a series of
rectangles (3 across by n down) starting about 50 pixels down from the menu.
This is, in fact, what happens in the 6.x browsers (IE 6.x, NN 6.x, Opera
6.x), and in IE 5.5. But, in IE 5.0, those rectangles start about 2,000
pixels -- that is, about the same height as the current collection of
rectangles -- from the menu. So the IE 5.0 user sees a huge bit of white
space, and must scroll down to see the actual content (which in some cases
they probably won't do).

This situation really perplexes me. The page structure goes something
like this:

<!--The main container-->
<div style="position: absolute; width:550px; top: 50 px; left 100px">

<!--The series of rectangles-->
<div style="float:left; width: 170px; height:200px; border: black
solid 1px">
<div>
etc...
</div>

Any clues?

Thanks!
