“more” tag in Atahualpa crunches side bars

I tried to use the ‘more’ tag with a post in my blog http://www.cookswell.com and when I publish it the sidebars, both of them, move over and align in the center column. I used the Elegance them and it doesn’t do that, so I figure it is a theme problem. Anyone have that kind of problem and a fix for it?
