UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support PM not being flagged as read

I have the same issue with one user.

I can "become user" and see the problem as well.

I sent another message and read that.

Still blinking.

It's like a counter is off by one somewhere.

Perhaps if another user sent a message and then deleted that message in a thread before he read it, it would cause it?

There should be a Mark all read for PM's.

Any ideas how to fix?
