Issue in IE8

Experiencing issues in IE8

Main Menu only HOME shows - highlighted - all other link text is black - if you mouse over it drops down.

Alignment is all over the place - main wrapper not centered - goes flush left

GK Tab - set to slide right & left - but in IE8 it goes up and down

all modules appear to have suffix - border1 asp border2 badge-hot

looks awesome in firefox and chrome

am I missing a css file or something?

SOLVED - I figured it out - we use openX ads manager and the invocation code was placed in the index.php file vs the layout/default.php

once placed in the correct file and between the head tags everything worked fine
