New Posts wierdness in 3.7

[cheesegrits]

I'm wondering if anyone else has noticed some flakey behaviour with New Posts in 3.7.

Some of the time it works just fine. Then for no apparent reason, I can hit New Posts, get the list, go off and respond to one of the new posts, hit New Posts again ... no new posts. If I check "Todays Posts", they've all moved into "The threads below have not been updated since your last visit or since forums have been marked read."

But if I then check forumhome, those same forums show the "New Posts" icon.

I'm seeing this behaviour on several of my sites which never had this problem on 3.6.
