Thanks for your help Travis. I do use Mozilla for testing scripts (as well as Opera) but in this case the page is on our Intranet which only has to work in IE.

Further to this I've tested the page in IE 5.5 and 6. In 6 the height works but 5.5. is buggy (but, as you know, 6 is buggy too ) but I still can't get it to align correctly in the Div.

I did find a way around it though. I changed the Div for a table... not Ideal, but it worked.

If anyone has gone any other ideas I'd be happy to hear them.

Cheers
