In the past few weeks, posts I've already read have been regenerated as unread, i.e. as red numbers on my Home > Forums page, and with "New" stickers attached to them in their respective threads (*), at least twice, and I definitely refreshed Home > Forums, probably more than once, before the re-appearances.
Is this an FTM cookie issue, or is it rooted elsewhere?
