"Mark all threads as read" does not work in the "new" BOINCstats. Don't know if it worked before.

Some old threads lost their mark as read (as they were before). So i would like to use the mark feature.

Probably a cache issue. I'll try to find it, BUT: I logged in with my test user account which has never read a thread, and the "Mark all threads as read" worked just fine. I then logged in as you and all threads showed as read.

After logout and login the threads are still marked as unread.

This time the "Mark all threads as read" link worked (without the need to reload the page).
