I've had same issue, updated to latest version and lost threat.
I was actually on hunter at the time and decided to be clever and update it for a semi KZ pug. I did notice it showing threat after the fight, but all options looked normal. Frankly bollox though as I pulled aggro twice and had no warning messages. What is the point of showing it after the fight as thats fook all use for both a tank and DPS? assuming it worked anyway...
Tried old version and ditto, every so often it works for 5 secs then just goes dead. I was planning on digging something alternative out for KZ/ZA on Wed, but any suggestions as above would be appreciated.
