There *is * a minor bug with the "unread message" indicator, and I plan to fix this, too. It sometimes happens that the tracker cookie gets set to a time in the future for some threads, causing new messages to not be indicated.
I notice that if I click on the light blue, it no longer marks that message as unread. But it also doesn't mark new messages in the thread as unread (at least for some time, often days).
Is that the "bug" you mean?
If it is, please don't fix it. It's not a bug, it's a feature
It makes it easier for me to ignore a thread that I wish to ignore.
