Setting read-only permissions

[mrbiggs]

I'm trying to set up a database with a guest and an admin user, and the guest is only to have read-only permissions. But when I go into MySQL manager to try it, the changes don't stick. Is there something I'm doing wrong?

I tried this by going into Advanced Settings, picking the user and database, and then switching from ALL to SELECT. I click on Submit, but nothing changes.
