I previously asked the question below. The fix suggested worked to sort out the IE6 problem but unfortunately the fix made it so that IE7 does not display the drop down menus correctly - they go under the DIV "slogan_section".
The fix was to remove position:relative from .top_menu.
"I have a problem with 'Extended Menu' for joomla not working on IE6.
I have tried the :hover fix for IE6 with no success.
The menu does appear as a link (hand cursor) for a millisecond while the page loads but after that you cannot click on the menu titles.
I'm not too bothered about the drop-down bits of the menus working in IE6, as long as they can click on the menu titles.
The website is at www.caldicott.com
Many thanks in advance for any ideas."
