Otherwise, you can go through those tags that have the 'onmouseover' events and add an 'onmouseout' event to each one saying to hide the menu that you've just shown.
The first option's better, but the second one would be quicker to implement right now.
hmm, i tried an onmouseout, but it hides the verticle menu after the mouse outs from the first item...if u try the second menu item, which is drop down, the firstitem works, but the minute you move off the first item, to the second, it hides the whole drop down...
