CSS in my list

I am a little stumped and looking for some help with my list. It is found on http://directory.wineography.com/sitemap.htm and the problem is that in IE not all the arrows are showing... Is it an IE bug or is there something that I can do to my css file?

Thanks!

It looks like a bug.

Maybe it should worked with <img> tags, but the page will load slower.

No that will be far too slow on such a big site map. There must be a fix for it...

I will ask a person who works with me (today he is late) later and I'll let you know if he knows :)

Thanks Nick!

I got it working now! Thanks for the help!

I change the CSS around and added:
#sitemap { position: relative; }

Oh. Good :)
