Yep, I was grouped, I targetted our main tank who had an enemy that they were attacking targetted. I tried this many times throughout the course of the evening, alt+T'ing each time to see if I could bring up the implied target window... each time I confirmed with the main tank that they had an enemy targetted and not a group member... (also helps that I'm married to the main tank, so I could see the monitor to see what was going on and confirm the target)... anyway, silly little issue that I'm having with this. But, as an enchanter (this is actually Phaydrae having this problem, not Thander), having the implied target window is quite important and I've come to rely on it to "check up" on my group members, but only when we have mezz breaking issues.
