OK. This has happened not once, not twice, not five times, but too many to recall. Either a kitten picture will show up in the list of recent past photos but I will never have seen it before or, as happened today, the picture I saw when I went to the page this a.m. (7 a.m. CST) was different than what it was at 9:00 p.m. last night. And now it has changed again, presumably at the normal time it is supposed to change!
Can anyone offer an explanation for this phenomenon that does not include a recommendation to me to seek out psychiatric help? (I regularly empty my cache).
