bg1 distorted at the right end

Hello,
First of all let me thank you for a great template.
I am running Joomla 3.1. My problem is that bg1 is distorted at the right far end of the screen. The other background pictures are distorted as well but they are less and less visible because the portion distorted is smaller and smaller.
All pictures are of course the same size, 960x542. Nothing is changed except for template_css.css, i added the fix for removing spaces between menus: #flashes.menu > li {border-right:none !important;}

Any idea on how my problem can be solved ?

Thank you in advance,

It looks ok?

Hi Ivan and thank you for replying. Check out the outer edge to the right. About 5 to 7 pixels are not aligned.

Hi Ivan, never mind, i put back the white spaces between menus. It looks nice with them as well.
Problem solved
