Hello there.
I've been working on this site:

I have two frames: a slim navigation frame on the left, and a main content frame on the right. Both are a slightly different shade of green, and I want a nice crisp thin black line separating them.

I've managed to get exactly this effect in Safari, Firefox and Chrome. IE however renders the frameborder entirely differently. I am prepared to employ some conditional CSS depending on browser, but for now I can't for the life of me work out how to get IE to give me a thin black line separating the two frames. Is it possible?

Many thanks.
