Yep, I noticed that.  Again and again.

Well, as long as you ask, I *hate* the "connect new object of the same
name to any killed object" behavior.  Fact is, in the "heat of battle" 
on SAR missions I often get a point wrong the first time I enter it (perhaps 
I get fat-fingered and enter 35d instead of 34d in there, or somehow
delete the W in the longitude and wind up with an object in China), and the 
only way to clear the mistake off my display is to kill the object, then 
create a new one with a different name.  I would be very happy if Xastir 
would ignore positions in the database for killed objects, and only display 
the ones that are not marked as killed.

Persistent display is good, too --- don't display killed points before or
after the restart.
