** Update **
I have been able to get the menu items visible and working, however, behind them is a background image that has vertical dotted lines to separate each menu button. In Firefox the menu states are spaced perfectly, allowing the dotted lines on each side of each menu button to be seen. But, in IE the menu buttons have been indented (not sure of the right word) from the left, covering the dotted lines up.
Any suggestions on how to fix this? Is CSS always read differently between the 2 browsers?
Cheers
