[jQuery] borders work fine with all browsers except IE7

[Namlet]

I have a site with several borders that are part of jQuery commands.
One has rounded corners, others don't.  IE7 doesn't render ANY of
these borders.  There are two divs that are not touched by jQuery, and
their borders work fine.  Everything that has a jQuery click event, or
rounded corners has no border at all.  Any ideas?
