Shift+M to bring up zone map, top left allows a menu to unlock the map, change opacity, etc…
If I ‘Unlock the map’ it centers to the screen (I wanted to put it in the bottom right corner that doesn’t get anything else placed there by the game) and is immovable.
The hover-menu for the map options moves to the very bottom left of my screen, and is only visible when I have the pointer over the ‘X’ on the zone map, now in the center of the screen. The hover menu is barely visible and you can’t interact with it (as your pointer is so far away).
This was on a fresh Alliance Shaman, so, I deleted the character and remade it. I experienced the same issue.
At that point I uninstalled BC and re-installed on a different drive.
Opening the game and creating another Shaman the same thing happened; zone map comes up, attempt to move, it snaps to the center of the screen and the hover-menu is not connected to it any more.
