Immediately after bm.AddNew bm.Position is 1 and so is dv.count, but 
only in that one form, in all others it's 2 (or in general bm.Position + 1).

Yes. I get "Object reference not set to an instance of an object" 
instead (in the one form, not in the others). And while there's a new 
entry in the grid, it doesn't have an ID, which is supposed to come from 
the database (an identity field) (in all forms).
