This morning all of sudden my Notes refused to start with error msg like “Database is already added to workspace”
only solution for now - delete desktop6.ndk 
.
Please advise if it is possible to “fixup” desktop6.ndk or pull info from it.
yesterday I’ve just resorted DB icons on workspace “nice way” . And now about 400 DB icons are lost.
Anyway, I can open this desktop6.ndk it as Notes DB and copy my private Views and Agents from there
maybe it’s time to migrate to bookmarks?
