sidebar go down only with post view

Hi!
I just customize the Revolution Church Theme for my website http://www.blackberrylatino.com and is working great, but when I click in a post the sidebar goes down ..
http://www.blackberrylatino.com/google-latitude

Only in the post because if a list a category post works fine
http://www.blackberrylatino.com/category/blackberry/

With pages also work fine..

I hope somebody help me
