CSS absolute positioning in IE4 & IE5

I am having problem with absolute positioning in IE5 and IE4. Basically I am using a pop up menu which is placed at absolute position with in a background.

but 69 pixels from top is different in IE5 and IE4, so how do I make sure that both browsers show them at same positon.

i hope that i have made myself clear.

edit:
just noticed that



is different in both browsers as well. IE4 is putting less white space at top than IE5. is this causing problem ??

As an alternative to absolute positioning I use transparent gifs to position elements on a page.

there should not be any differences with positioning in version 4 and 5 in internet explorer..
this should work the same:

<div style="position:absolute; top:50px; left:50px"></div>

but post some code please....
