Nope.  When you deleted an object, Xastir comments it out in the
object.log file.  This is to assure that if Xastir gets taken down/
restarted, that the object won't come back on its own.

You need to hand-edit the file currently and uncomment the last
instance of the object in the file.  Earlier instances might be
earlier positions of the object, etc.  Every time you modify an
object it should get another entry in the file.  When you delete
it, ALL lines referring to that object get commented out.

Here's where the trouble lies.  You uncommented both the original
object and the killed object, so at this point you should be
transmitting both a live DARS object and a killed BBY object.
The BBY killed object actually does get transmitted, and knocks
the object off of anybody's screens that might still have that
object as "live".

To do this next time, uncomment those two lines and delete the
line with an underline after the name field.  Also try an Item
and get familiar with their format.

Eventually we need to code up a way to bring an object back again
from the View->My Objects dialog.
