Targeting Issues

[BlackstoneKrull]

My room mate is having some probs with the targeting from both the Raid Window and the group window. Seems that by left clicking on a character's name in either window does nothing the ony character it works on is himself.
He can direct target or use the command /target Whoever. Has he turned something off in the UI or the game? I cant figue it out and before I reinstalled the UI and maybe even the game I thought I would let the Pros give me some advise.
Thanks in advance
