I am setting up a new computer, using thunderbird again. For some reason, even when my old computer is turned off, the emails come in bold, showing I have not read them yet. Then, even before I have a change to read the email. it becomes non bold, like I have read it.

Can you help me with this, I use fatcow. On my old computer, the messages would stay bold until I had read them, which I what I am trying to accomplish. Thank you.
