We are running Zen Cart 1.38a have just installed IE8 to check that our site is displaying correctly but we have discovered a problem with the display of the Category Navigation tabs under the flash header.

In FF and IE7 the tabs display as 3 rows but in the new IE they are stretched out into one long row and a scroll bar appears at the bottom of the page. Switching to compatibility mode solves the problem but we really need to find out why this is occurring. We would appreciate any advice.

The site in question is w w w. t a i l o r m a d e n a i l s .co.uk
