tfolock
Description
Implements a frame overlap lock for a frame, whereby if another frame is moved (so that it overlaps the current frame) a warning will be displayed. The warning gives you the opportunity to override the overlap lock to allow a new overlap position or to refuse the overlap, thus preventing accidental movement of relative frames.
