I had posted earlier this month that I was having trouble with my secondary sidebar on my blog. I have fixed the positioning issue on the x-axis, but I am still having trouble with the height.

I am using the sandbox theme and It is set up with a left column, main copy, right column. I have the margin on the secondary nav bar set to -100%, the problem is that the positioning is not consistent on all browsers. I have tried to change the width of the div#container, but then it screws with the primary sidebar. Anybody have and suggestions, it would be greatly appreciated.
