I have a problem. Let me show you this picture:

Both are scrolled up to the top.

As you can see one the left side some of the text in under the header, and not completely visible.

The left picture is at the first load. When I go to another page and then back to home it's OK (see the right).

This app/site can be found at:  http://www.cassy-web.nl/app/vanengelen

Thanks!
