1 px horizontal line in my footer??

I've put a snazzy corners border around my footer. The only problem I've got with it is there is a 1 px white line under the links. It is deffinately not caused by the snazzy stuff. I think that it has somthing to do with the #navSuppWrapper or the #navSupp, but I can't find anything that would be causing it. I can't even find the #navSupp in the stylesheet, so I added:

#navSupp {
background-color: #d2e7bd;
}

to no avail.

Any ideas on what might be causing this irritating white line? Are there other classes that effect the layout of the footer?

Thanks!

I can't see the line in IE7 or FF2.

IE6 is definately a mess - IE7 shows the line you are talking about. Afraid I don't have a good suggestion to fix it though.

Thanks,

I've noticed that it is not there with FF3, but shows in IE7. Very annoying.

On a side note:
Now I've got a gap between the #logoWrapper and the #navMain. It shows in IE7, but not in FF3.

AND the font I'm using sucks in FF3, but is nicer in IE7.

ahhhhhhh!

Might want to start with fixing the html errors - http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fwww.maestrosteachingsupplies.net%2F

whoa....

Ok, it was caused by my choice of font. I changed the font and now it's gone.
