The forum isn't remembering topics that I've previously read and is showing them as new messages. Has something changed? I remember it doing this before.

Edit:
Must be a Google Chrome issue. I browsed the forum with Firefox and it's working correctly.

Update. Problem is not with Chrome. The problem is with the way the NEWBB module for XOOPS is storing the viewed topics. Viewed topics are stored at the client in a cookie called "newbb_topics_viewed". After viewing a lot of topics, the cookie reaches maximum size and can't store any more history.

Edit: I ran the cookie test at http://myownplayground.atspace.com/cookietest.html and these are the results for Google Chrome 18.0.1025.142.
