Very strange.  It happens for me every time.  I hit "[" on one star, then move 
to another star and hit "]".  I get something near zero every time (like "0d 
06m 14s").  I can workaround it by left-clicking at some point between the 
"[" and "]" events; it doesn't seem to matter where or when I click.

Perhaps related: when I press "[" on an object and then move the mouse away, 
its Transient label does not fade away, and I don't get a new laabel when 
hovering on another object.  Again, if I left-click somewhere in the map, 
then the first object's label fades and I can then invoke new transient 
labels by hovering.  I don't know, maybe the problem is in the transient 
label stuff.  Strange that it isn't happening this way for you, though.  Has 
anyone else tried it?

Jason
