Mr. Vachek would be correct if not for the bug we have mentioned. In this 
case, it is likely that the keepout layer or other board outline is a 6 mil 
track, and the incorrect snap to the edge of the bounding box causes 
everything to be off 3 mils.

His experience here shows the nature of this bug: it only appears when the 
paste or move is above a certain complexity *and* snap to center is turned 
on. Below that complexity, you get a bounding box only when moving and 
there is no snap to the edge of the paste extents. So a designer can work 
for quite a while without ever seeing the problem. Then it will drive him 
pr her absolutely nuts.... unless he or she faithfully reads this list, in 
which case only one of us ever needs to go through that phase of temporary 
insanity.
