I use the default mouse movement and camera settings. After the 10.1 update the keys seem to be unbound (I cannot hold both mouse buttons to move, use the mouse to turn, or use the mouse to change camera angle).
Not sure how to proceed here because I don’t know if it’s a bug or if the keybind system has been changed significantly this patch.
EDIT: I dug around in recent threads and the issue is the Map Coords addon.
Leaving this up so it’s easy for other folks to find the problem.
After today’s patch one of my toons lost the HUD settings. Some of my action bars were gone, the others were not in the original location. The mini-map is now in the middle of the screen & can not be moved back to it’s original location. The mouse doesn’t move the toon & clicking on items with it as no effect. My other characters have no problem, just my mage, Niteknight.
