Hello Sitepointers.

I've posted a thread about this site and got some help from some of you, which I'm thankful for. I've adapted the site as to the advices.
The site looks ok (I'm still in the draft zone) but the basic-layout should be fine.
The site is on: www.advocaat-kvd.be
Problem is now in Internet Explorer. the header should normally be in grey, and filled up with the headerfill.jpg.

I didn't have the problem before I adapted some things, but I can't seem to find where the problem lays. I find it odd that its a repeating jpg he doesn't show.
Can you guys give me some explanation why this happens and how to fix it?

In attachment my css-file.

Any other tips also welcome...css.txt
