I KNOW this was reported before, I think, but my search could not reveal the prior thread(s)

After a new post is made to a channel forum, a notification alert icon appears in the channel name field.

After the forum is visited, the icon goes away.

But some minutes later it comes back even when there is no new post since last forum visit.

I am sure this is on the fix it list and it's not a critical issue. Just as memo.
