Blender 2.5, selection border gone.

In one of my .blends, the orange selection border has seemed to have disappeared. I opened it in other builds, and then within those builds opened a new file and the border re-appeared. This is really annoying because I can’t tell what I have selected.

There is a selection box for outline selected in the Display settings of the Properties panel (keyboard N)

Oh wow…how did that happen? :smiley:
