I've noticed my dropdown menu works perfectly in chrome, ff and opera but in IE its a mess - BUT! it works in my 404 page.
Examples: http://www.raal.co.il/ and it works in: http://www.raal.co.il/asd
The weirdest thing is this: I've copied the 404 page's code to a blank page and put it in the home page - and it still doesn't work!! like the address is related some how.
