Motion control bounding boxes disappear
If the timeline is played while a clip's motion controls are selected and the blue bounding boxes are on the program monitor, the blue bounding boxes will no longer show up when other clips are selected, double clicking them or clicking their motion controls in the Effect Controls panel does not bring up the bounding boxes- the sequence must be closed and re-opened to bring them back.
@Franklin Nin that didn't work.

Just select the Motion Control of a clip and play it a bit and the Bounding Boxes will appear again, but I agree that this is a bug.
