I'm still experiencing this problem with version version 1.5.0.9 (20061220).
I synchronize the .rc file across several computers, and then read the news from all these computers. unread messages are correctly highlighted. So if I show only unread messages I actually have only the unread messages. But if I show Threads with Unread, I get also threads where all messages are read, in particular if on that computer the first message of the thread was never opened (it was read on another computer).
