Please help me to defeat Mac IE5 (CSS problem)

Having fixed the last problem (http://lussumo.com/community/comments.php?DiscussionID=1022) I have one final bug having spent 2 days solid re-arranging all the code... Every browser I've tested is working now fine, apart from Mac IE5 which is showing the hidden parts of the topnavbar at http://www.thirdeyedesign.co.uk/beta/macmic_website/test2/test_layout_1.html Not fixing this is not an option, so if anyone can help me get this right I will owe you big big big time! (I did fix this earlier on in the project at http://www.thirdeyedesign.co.uk/beta/macmic_website/developments.html but can't seem to work out why this page works and the new one doesn't)

:-) I managed to fix it last night, phew. And it's the first time I've got something to validate as XHTML :-)

I like your designs. Really nice.

Thanks giginger! I've been working with someone else in the office on this so can't take full credit for the layout... In fact a 3 column grid with fixed height boxes was not my idea, and definitely not the easiest thing to put together :-P This is my first time at using css for a commercial project though - it was a bit scary to at first be honest, but a real learning experience that's for sure! I quite like the fact that the design has absoluetly none of the stuff that is trendy in webdesign at the moment (apart from the simplebits icons!)

Now I have some very stange behaviour - the height of the layout at http://www.thirdeyedesign.co.uk/beta/macmic_website2/ changes to it's correct value, but only when you refresh the page... This only happens in some browsers, is something collapsing, and could it be related to a minimum height hack I'm appliny to some of the layouts.... totally stumped again :-(
