I have lots of my subscriptions showing unread articles when there's no articles at all, and others that I know have recent articles that are not showing up.
I've tried exporting the hierarchy of ~250 news groups, deleting them and reimporting them, which cleared all the erroneous unread messages, but now all subscriptions are completely blank. I would have expected to Vienna to think that they were entirely new subscriptions, and reload the history for each one. Am I wrong in that assumption?
Is there some other setting/cache file I can clear to force it to reload everything as if I'm starting from scratch?
TIA for any advice!
