Problems with minimap...kinda

[Clare]

Ok, i run several different characters, including a couple DKs. On one of my DKs i have this problem with a big circle with a ? in the middle showing up right on top of my minimap, blocking most everything. i'm not sure that it is a nUI issue though. Clicking it does nothing. i can't move it. Id i open my work map, Metamap, it apprears on that in the same place. i can reload my UI and it will go away for a while, but then my titan bar will disappear until i reload again. Then after a bit it comes back. i have no clue at all what this could be. Any ideas?
