Cannot Save Window State

When I attempt to save the window state, I get the following error message: “Required folder not found in the bookmark database. Please upgrade to the latest bookmark template”

Our welcome page is based on the 6.0.1 bookmark template, so I replaced the template with the release 7 Bookmark.ntf, but even after replacing the template I get these same errors. I find nothing in the logs to give me any further insights into what the problem is. Has anyone else seen this problem, or can anyone provide any insights into what the specific problem is?

check to see if autosave.ntf is present in the notes data library
