Watch out for the above control, it appears on the SPS (home page) area template but not on the others.

On our customization of the area templates this tag had been inadvertantly removed.

Bad things started to happen, especially with my replacement content editor web part, this used the WSPC save properties capability, it worked every where but the home page. It used to work on the old home page. Sure enough replace the page it works.

That control is the culprit and like so many other things in sharepoint no documentation on what it is, why it is, or how to use it.

Thanks again MS.
