Page background, half disappeared?

Hi gang,

This occurs fairly regularly. I've got a page background (a gradient). The site is loading fine. And then, when I sometimes do adjustments to a page ... the page background is not the FULL page, but only a portion of the page.

I go back to the iWeb project and redo the page, alter it enough so that I can reload it as a changed page ... and sometimes it gets rid of the partial page, and sometimes it doesn't ... the partial page is still there.

If I do the page over and over again, eventually I get the full page background.

I'm wondering what might be happening here.

All ears, Ben
