You're right, in the final few months they showed it, in the spring of 2000. They were really rationing it in those days, presumably to drag down the figures since they were about to lose it - much like when the Beeb swapped aroud Neighbours and Doctors when Neighbours was about to go. That was the same time they dropped the lunchtime showing in most (but not all) regions, as part of a brilliant daytime revamp in March 2000, when they moved Loose Women to 10am and Trisha to 2pm, and then two weeks later, moved them straight back again. Ha ha ha.
The year before they also had to drop it for a month as they were catching up too quick, but not in the summer, during April I think. They replaced it with Lie Detector, the series from L!VE TV, which flopped massively and they took it off before the month was out.
I've said this before, but since we've started a new part I'll say it again, also in 1999 they took the lunchtime showing off for a week for snooker and William Phillips in Broadcast referred to "a real display of true viewer loyalty" because the teatime ratings skyrocketed, it had almost the same number of viewers for that one screening than it usually did for both put together, suggesting that absolutely everyone who normally watched at lunchtime watched at teatime instead, the difference presumably only being those people who watched it twice.
It used to be Home and Away had a massively loyal audience, they can't be many shows that could cope with a year's break, as it did when it moved to Five. And ITV should never have dropped it as it left a right chasm.
