Javascript Internet Explorer Problem

I thought you might be able to point me towards the solution without even seeing the code but I�ll be happy to post it in here anytime.
The problem is a javascript menu which basically does the following: whenever the mouse cursor is moved over one of the links a submenu (a picture with paths in this case) appears.
This menu works perfectly with the latest versions of IE and NS on a windows machine but has a very peculiar error when I try to load the site on a Apple Macintosh computer using IE.
If it didn�t work at all - that I�d understand but the very strange fact is, that - whatever patch or IE version I use- only the first submenu appears. The others (4 in total) never do. It however works If I open it using the Safari browser.
I�m not a very experienced javascript user and put this one together based upon a tutorial I found on the net some time ago. I�ll post the code if that helps but i figured this might be some well known (at least to those who know more about js than I do)incompatibility.
Thanks a bunch!

Post the code here since I am not a mind reader...
Either post a link to the code or
post the code here by placing it in code tags and you may have to run it through the escaper in order to post it.

IE on the Mac has a lot of known problems that Microsoft will not be fixing since they have deprecated that product. The bad news is that any problems caused by deficiencies in the Javascript engine will never be fixed. The good news is that IE doesn't get used much anymore on the Mac. For the Mac, your time would be better spent ensuring that your pages work well in Safari, Mozilla and Opera.

here comes the menu:

Like I said I�m only a beginner so this might not be the most effective way of doing this. However it seems to work with most browsers and if there is some little trick that would make it work with IE for Apple Mac as well I�d be most grateful for your advice!
thanks
