omg I have not seen frames in years. If you are planning on designing more pages please please learn to use div's also. Frame layout is not good for
SEO.
I see the rounded corners. Did you uses that roundedcornrr (sp?) service online? I'm wondering because I have used it too and the default code it gives you has a bug when viewed on Firefox. Like one of the frames pokes out a bit. I don't know how much of a perfectionist you are if you feel the need to fix this, it is not a major issue. I added a picture to show you what I mean.
hope this helps good luck with everything
