How do i fix this? i tried a few things but haven't had any luck.. the button remains in the same place and remains after i thought i disabled it in functions. Note: this only happens when you have a good number of tabs open so the plus sign moves under the "Move" button and stays there. See attached screenshot.

I have a possible solution to your problem but as your attachment is protected and only seeable to DF staff, I cannot see if what I think you should do is appropiate......
