Threat Meter Issue

[wintermute218]

First, thanks for the awesome interface and the speedy update release.

I'm having an issue with the threat meter... on one of my toons, a paladin, the threat meter seems to be working correctly. On another one of my toons, my Swashy, the threat meter is blank.

Is there some class distinction between them or is somehow the meter broken for one toon and not the other?
