>I did some tests tonight. In that thread, there are two messages not created by you. One is unmarked. On that one, when I simulate other your account, I have the ability to mark the message as a help. On the other one, if I test as if no solution would have been given, I have the ability to mark the message as a help as well. Everything works as expected. This routine remained unchanged since a year now.

Thanks for looking into it, Michel. It beats me, whatever happened. I'm not gonna worry about it, especially since you've tested.

Anyway, if there really is any little glitch anywhere, now a lot of UT users have read about it, and may be noticing the Points buttons a little more, and report if anything unusual occurs.

Also, the thought occurred to me that this might possibly be related to local page-caching on my end...
