Problems with Office Web Component

Hi guys,

I'm using the Office Web Component to use the Excel-in-place presentation for my planning layouts in BPS. In the last screen of the layout builder I've freezed the columns, but when I call up the web layouts the freezed column is NOT freezed.

Does anybody knows why freezing columns or rows does not work in the Excel-in-place? I'm using Office 2007 under BW 3.5.

Thank you very much!

Clemens
