Intermittent false new posts notification

[weavertheme]

Since the recent update to bbPress 2.6.3, users of my forum are getting false "new posts" available graphic indications, even after they've open and read a topic. We can't seen any pattern.

Sorry can't provide more specific details, but this is happening on a fairly busy tech support forum (100+ visitors a day, maybe 5-10 new posts per day, tens of thousands of existing posts/replies).

Have you gotten any other similar reports? We just updated to bbPress 2.6.4, so will see if that helps.
