[Evolution] "Generating message list" won't go away -- possible database corruption

[john lauterbachandassociates net]

RE: evolution 3.20.5

evolution has stopped working correctly -- likely something happened 
when using very slow connection when traveling.

folder properties indicate all e-mail still there.

have tried correcting any database errors with $ sqlite3 folders.db 
"pragma integrity_check;" on folder containing folders.db

program returns an "ok"

I then renamed folders.db to folders.dbb, killed all other evolution 
related tasks, and restarted evolution.

No luck, and newly built folders.db much smaller than folders.dbb

Have made folders.dbb folders.db, redid the integrity check shown above, 
and restarted evolution; sill have generating message list.  Most all 
commands on drop down menus do not work.  Cannot even get Help About to 
work.

Would appreciate some help on getting evolution back running correctly.  
Right now working from webmail applications to receive and send email.

Thank you,

John
