Looks like there's not going to be any updates to nUI or the plugins tonight as I had previously posted. I can't get logged into any of my realms and I've had 3 hours of sleep since Monday. I'm gonna see if I can catch some Z's and get on the servers in the early AM or after work tomorrow for those fixes.
I have noticed one minor problem. When I was in a 25m Sarth raid last night, the "target" window wasn't displaying the marks, but the HUD and player target buttons were. Just a minor anoyance, but I do want to say, nUI was my only 3.1 ready addon when it went live yesterday. Even the Ace3 framework was busted!
