Can't disable IndexArtwork in 2.2

[pgbj]

I upgraded from a full license 2.1 to 2.2 and all the index entries had artwork added. I read the release notes and saw that this was enabled in the migration to 2.2.

However, if go to the server options (either web page or minimwatch) and try to delete the "indexArtwork=auto" entry it just puts it straight back in - as if it is the default and you cannot set it blank.

I tried "off" but that was not allowed; as a workaround I have set it to "folder" (there are no jpgs).

Also had a problem with my "displayName=Peter's Music". This is shown in the web page as "Peter's Music". One time when I saved and restarted this was actually the string used in the log and at the control point. I am not sure the exact circumstances because I have it back now ok.
