Several issues.

1) "Overwrite user fields in view to show realnames option" refuses to save. I click the radio, hit submit and it clears.

2)New users are not having their real names used. I have to recalculate names every time a user is added in order to have real names evoked on that user.

3)Upon recalculating names I receive the following error.

warning: Invalid argument supplied for foreach() in /mnt/mysite.com/web/content/sites/all/modules/cck/content.module on line 1764.

Excellent module. I have been waiting for years for something like this!
