As with any other Qddb database, you can stabilize
your database from the command line by typing
qstall <RelationName>. Alternatively, inside a Qtime
application, you can click the Misc/Restabilize menubutton
to stabilize the Qtime database. Note, you must be in
Search mode before the Misc/Restabilize menubutton
becomes available (i.e. unstippled).
