I just tried it and it works fine here and in Mozilla browser.

When you say it doesn't show up, do you mean that the msg count and "last post" columns for the thread aren't updated? Or that the "New" flag doesn't appear next to the thread? Or both?

In my changes trying to resolve the login problem I didn't make any changes to the message forum so I wouldn't expect any changes in behavior.
