I had another problem (with Win32 0.9.8 and some nightlies before and after 0.9.8) with underlining subject. Normally subject is underlined and thread icon shows green arrow when there are unread messages in that thread. However, sometimes, even when there are no unread messages, subjects are underlined and icon is with arrow. Is it a known bug? Receiving all messages and marking them read (Message/Mark/All Read) does not help. Restarting Mozilla not always helps. I'm not sure if these problems are connected, but sometimes folder name remains bold even if there are no unread messages in that folder.
