"Subject" question

[desmo2]

In the forums under thread title, or 'Subject,' I noticed that some subjects are in blue, others are in green. When I click on a green subject and view it, then return, the subject has turned blue. What do the colors mean?

Also, occassionally an old topic will pop up with a "new" post indicator next to it, but there have been no new posts or modifications to the thread. What gives?

Green means you haven't read it yet, blue means you have. If you erase your cookies, it can't tell what you read last time and doesn't know what is new to you.

Hmmm, gives new meaning to the phrase "toss your cookies." ;D

Odd. I haven't erased any cookies, unless some are getting wiped out by some unknown process. Guess I'll have to live with it, trivial but somewhat annoying as it is.
