Can't resize my page: Internal program error 1420.k.No.ar ?

Hi Xara folks !

I have problem with resizing my page. Let me explain: On my page I have soft group on the top (header) and soft group on the bottom (footer). In XaraWD7P I have aligned it respectively, header aligned to the"top edges" and footer to the "bottom" edges. Now, when I want to reduce the height of the page and "pull up" lower edge of the page, the footer goes up, along with bottom edge, but in that moment I receive the message: "Internal program error 1420.k.No.ar", and objects from the top (header) are moved down, some of them are not in the earlier position with the other objects.
Are there any suggestions ?

I do not if this will work, but maybe you could create a new blank page and adjust the height and then copy and paste the content from the problem page onto the new page. If this works then delete the other page.

Hmm .. interesting idea :-)
Thank you.
