Could this problem have occurred in V2 or V3 equally?
A professional technical person, it seems, ought to have foreseen this.
A bit like the "millenium'' bug, whuch was foreseen so long ago, a whole 17 years.
I am only saying here that if V3 did not specifically cause this, we should not get sidetracked.
