It was rendering fine on my machine the first time, but I ran your HTML through my browser's validator and I saw some problems with the second TABLE tag, which had a HEIGHT attribute set to XX% which is not valid. I took out the HEIGHT and WIDTH attributes for both TABLE tags since they really don't serve any purpose here.
Let me know if it fixed it. If it didn't, then I don't know what to do. Thanks, AM
Yes, it's just what I was expecting to see. Thanks so much for the quick response.
