Scenario: A user is subscribed to a particular forum. A topic within that forum is updated and the user receives an update notification. If the user follows the link in the update notification to view the topic that was updated (i.e. the viewtopic.php link) the notify_status in the forum watch table is not cleared. The user must go to the viewforum.php link in order to clear the flag. As a result any other updates to this forum will not generate further update notifications until the flag is cleared.

This is contradictory to the text in the update notification which reads "no more notifications will be
sent until you visit the topic."

Proposed solution: either the watch_topic_forum method in includes/functions_display.php needs to be modified to lower the flag in the forum watch tables regardless of the mode, or the function needs to be called twice in viewtopic.php, once with the mode set to topic and once with the mode set to forum.
