"_sm.length is null or not an object" error

Greetings all,

When I hover over menu, and then quickly move to a different part of the menu, this is the JS error I receive:

The JavaScript Error wrote:
Line: 20
Char: 9998
Error: '_sm.length' is null or not an object
Code: 0
URL: http://192.168.......etc.

Seems to happen only if I move the mouse quickly. Slow movement results in no error. Is it that something isn't closing properly on the open drop menu before new hover creates a new drop menu?

Thanks in advance,

We'd really need to see your page where this is happening. I've tried the sample in IE, Firefox, Netscape, Opera and can't reproduce that problem so there might be some other little thing that is causing it. Can you give us a sample page?
