Been tinkering with this for three hours now, and I'm at a total loss here.
The window is from Wiznut's UI. I took the buff's box and moved it to the right of the window. Target is at the top, HOTT is on the bottom. The window is designed so that when you target someone, a box matching the /con color of that mob or NPC appears behind the name and HP gauge. Previously, it was stretched across the entire window - now, it's doing some strange artifacting and stuff that I don't understand.
