the radio box which shows the players in range/etc, the box that allows you to join a staged mission both do not stay where you put them when you drag them. They also spawn really high up.
The R for indicating recording and the purple text when someone talks also is really high up. You have to look up to see them and they aren't dragable.
The box for saving films seems to appear in a good spot or it was dragged and has stayed there and the radio text box and messagebox both are dragable and stay where you put them.
