Maniac55 has hit the nail on the head. Most of us are just having a "whinge" because they replaced a working system with one that doesn't (yet - maybe). But, right now, there are some people in real hardship because of this and, not surprisingly, their mind is not going to be focussed 100% on the job. That is a flight safety hazard enforced on us by the people who will crucify us when something goes wrong! Somebody ought to have dusted off a copy of "distractions".
