Interesting point I hadn’t thought of – that certainly would account for exactly an hour, wouldn’t it? Yes, I’m set to automatically switch back and forth – typically Win does that on the first reboot after the scheduled change, which here is April to Daylight Time and Oct. back to Standard.
And without (so far) any virus warnings, there’s been no real reason to look in the chest other than occasional curiosity, so I haven’t a clue when the extra copies were put there. They’re gone now, anyway – and I’ll try to keep an eye open there next month when we go onto Daylight, to see if I get new ones again.
