White section in Header - top-left side and not top right (ie toplinks)

[Impromptu]

Hi all,

I have a strange white section in the header and spent a lot of time on this :(.

The white section is at the top left at www.supercoachscores.com

I have checked header_background and toplinks_background but that's not the problem.

I have a transitional colour via image in header_background.

Thanks

Cheers Jay
