Background images not aligning / jumping around

Hi,

Thanks for a great theme, I’m nearly there with my website redesign.

I have a problem, though – the section backgrounds I’ve set for the different sections are not behaving properly. If you scroll up and down the site you’ll see the background images don’t always line up with their corresponding sections: http://www.thereverseengineer.co.uk/

I’ve spent a long time trying to work this out – I’ve changed the settings for the sections and backgrounds to most possible combinations, but nothing worked. I’ve also systematically removed sections to see if it’s any particular section that’s causing problems – again, I can’t find anything wrong.

The only thing I can see that makes a difference is if I reduce the height of my browser window. At a certain height (roughly 900px high) the problem seems to go away.

Any help would be awesome.

Thanks,

Dave
