borders in Netscape 6

[tnsbuff]

Hi,

I have a page that uses css to define a 1px border around the outside of a table as well as the cells. In IE it looks fine, but in Netscape 6, the borders are darker/thicker, as if the borders are being duplicated. I've never really understood the border-collapse property. Could this be part of the problem, although I do have it specified as "collapse"?

Thanks in advance for any suggestions.
