Cant click names

Happy this got resolved for you.

Many times this is a case of a setting inadvertently becoming changed - some addons can even do that.

Just for a point of reference, if you ever find odd-ish things happening and think it could be addon related, a reset UI never hurts.

To do a full reset UI, you will want to save your addons in another spot if you wish to preserve them.

Then rename/delete or move your WTF, Cache and Interface folders while WoW is shutdown. Reboot your system.

Note, if you are running Vista make sure your permissions are set so it does not undo your changes.

More detailed instructions for different operating systems, including Macs are here.
