Navigation doesn't look right in IE (CSS problem?)

Can somebody tell me why the navigation (about, snow areas, condition alerts) doesn't work in IE?

I have been trying to fix this for days now...

Thank开发者_C百科s!

On your <a id="dd1" style="width: 170px;"> this inline style is creating the huge gap between the elements. I removed this in IE8's developer tools and it looked similar to how it appears in Chrome.

Remove this width from the inline style on each of the links.:)
