I'm having an issue on version Omen-r70687. The threat meter itself is resetting (stats) but the flashing red aggro indicator will not go away.
For instance, I was in Heroic Shattered Halls (as a Mage) and I pulled aggro on the last boss just before he went down (Bad Mage!). When I pulled aggro, Omen made my window flash red which is normal. After we killed the boss we all ported to shatt. I flew all the way to Netherstorm and my screen was still flashing red (never stopped). I had to log to get the flashing to stop.
