no, it is not altered, but its editation goes to the "white death" and of course my users try to edit that and then write me there is a bug

ok then ...
but what about the radio button, checkbox etc values like male/female? I can change it to other value, but I use this field (and many others) like searchable fields in the userlists - this looks like serious problem, you know what users can do

it would be great to forbide some fields editation. Similar problem is with URLs - CB offers divided field with URL and Website title ... the plugin loads only the website title without its URL
