menu dissapears on mouseover in IE6

[lovelyme]

In IE6 when you mouseover an item in the menu the rest of the menu dissapears except the item the mouse is on. Then if you click the item the rest of the menu reappears untill you mouseover an item again then again the rest dissapears. My problem is in IE6 only, the current browsers work fine. You can see an example of this problem at

Any suggestions would be greatly appreciated

Try to remove all IE filters from the menu_items.js.
