Ed,
Sorry, I looked at the URL in your second message www.box.com and that

In this situation look in the application/databases directory for a file with
the table name as part of the file name. Remove or move the file somewhere else
and then restart the web2py server. The table should now reappear and will be
empty.
You also need to consider the database type used by the application for the
model. The SQLite database has a transaction lock which will cause the
application to look like it is single threaded if the database is held in a
transaction pending state while the background work is performed.
Run 2 copies of web2py, one for the script and the other for the web site.
If the database is SQLite you will end up with blocking problems if the
background task takes too long.
You should probably check permissions and ACLs all the way up the directory
tree to the root of the drive. It is possible to apply an ACL in an upper
level directory and with a check box option cause that permission to apply
recursively to the whole file tree below.
I use PostgreSQL as well with great success. Another thing to keep in mind
is if you restart the database server and are using apache with web2py then
you should restart apache as well. The reason is the connection pool if used
