I wonder why is it working perfectly well when playing it on my Internet Explorer after opening it straight from my PC, but ONLY doesn't work on the same Internet Explorer if played through the Internet itself (after I uploaded files onto tripod's web-space).

In fact, that's why I had to download a file "csshover.htc" so the codes within this particular file makes it possible for this CSS based website compatible on Internet Explorer browser. Even the article on website http://www.xs4all.nl/~peterned/csshover.html explains the same, as how to overcome this problem, so I presume although achieving the exact result isn't quite a plain sailing however, there's a fair chance of getting it done. Over the coming days, I'll be exploring into it.

By the way, any other way of getting the same same result, since I've seen many website having exactly the same hover effect as in my "leftMenu", while browsing their website on Internet Explorer ???
