Sidebox category menu problem with IE

Hello, After adding a few products my categories Menu on the left seems to go wrong. In Firefox and google chrome it looks fine but in IE it plays and the menus dont drop down and it looks wrong, I even started a fresh with all the products incase something was corrupt and it worked up to about the 5th item. Please can anyone advise on this how to resolve? its the same on a second site also

Sorry, but we don't know what you think 'looks wrong' about it. Can you be more specific about what you're expecting ?
