Header in Coporate 2 with white frame?

I just installed the corporate 2 business template but around the front display there is a funny white frame. Can anybody tell how to elimintate this frame? Have a look at the attachement.

Details:
As it seems the red area has the exact same hight as the original sample front display. I included the module mod_gk_image_show in the "header" position.

Thanks a lot.

please add module suffix " clear"

So I changed the module class suffix to "clear" and furthermore, I had to move the module from the "header" position to the "header_1" position. Now it seems working. Thanks a lot

shouldn't have to move it thou...

also did you remember a space infront of clear?

I had have the same problem for some unknown reason. Haven't changed anything, haven't touched anything, but from one minute to the other the white boarder appeared. Solved it like mentioned in the previous posts. Seems that for some unknown reason the position has moved. Strange.

Boris: I would like to get in contact with you. How can I reach you?
