So we've had a few users complaining about the sorting that is done in the Attachments screen.  When the user clicks on the heading for "User", it sorts by Userid not username.  This displays some pretty poor results as far as our users are concerned, as it is not by username. 

Any idea's on a fix for this?

Instead ofsorting on the displayed UserName 'format' of the ID field, link the ID field to the USERINFO table.....then sort by Last Name First Name, etc. in the UserInfo table.
