Gets worse: The list goes back to July 29 only -- where are the unread ones from before that date ?
hmmm, but you're on PF almost every day? How are alerts going unread for over a month? btw, read, simply means generated by the popup or list. Obviously the system can't know what alert you've physically "looked" at.'Expire' meaning they disappear from the list -- but the counter still counts them as unread !
Yes, I experienced this same thing quite a number of times. I haven't had the problem for a couple months now, but I haven't posted much in the last two months. And it was rather problematic when it did happen=a long post with a lot of Latex would take a long time to convert it back to Latex, only to find the Latex disappear again before all the corrections were made. Like @andrewkirk I had to edit one post by starting a new thread and getting it completely correct before posting. Trying to make one simple correction to a post could cause the complete Latex to crash again.@Charles Link is above the issue we were exploring awhile back?
My problem is that sometimes when I edit a post, if I attempt to italicize, bold or underline even a single word or letter, then everything following also gets italicize or bolded or underlined.
