Have you upgraded your data directory? Try upgrading you bookmarks.nsf and getting rid of your desktop5 / cache.dsk files.

Did you convert the mail file to the 6 design? If so, you may need to go into the mail file and do the upgrade folder design to get them all. I have noticed if the mail file is open at the time of convert, the design for some folders do not get upgraded. Hope this helps.
