Rollovers working in all browsers but IE

Hi,
My navigation buttons have rollovers and are working fine in FF, Safari, Netscape, Camino but not in IE.
Not only that but there are some weird dashes appearing between some of the buttons. I do notice that the dashes disappear when I hover the cursor over some of the buttons. Can't figure it out. I'm a fledgling javascript programmer, extremely fledling...

http://www.potomitan.netI'm surprised that they work anywhere with that syntax. Ideally you need to change two things. First, images are best referenced via the document.images collection, so as an example your first link should read:

<a href="index.html" onmouseover="document.images.home.src='images/navbuttons/homehover.gif';" onmouseout="document.images.home.src='images/navbuttons/homeorig.gif';">
For this to work, you must change "id=" to "name=" in all the <img> tags. That is the simplest fix to get the rollovers working in all browsers, however without using preloading techniques, they may be slow to respond when viewed on slow connections.

I suggest you take a look at these:
