Hi,

I have a major problem with my header. If I go to one of the longer pages (the ones you can scroll down in) when I do scroll down my header jumps about 200 px down leaving an empty gap above the header.

I really don't know why it's doing that. Can anyone with more brains than me please check it out. This is a good page to see the problem, on first load it's normal until you scroll down and than back [urlhttp://www.ad-mineraal.nl/index.php?main_page=index&cPath=1_95_2[/url]

Thank you in advance!
