Sticky posts not threaded?

[Travis Cobbs]

First of all, they're threaded fine when viewing the post, it's just that if you have the message list display option set to "All messages in a topic, threaded", then old ones don't show up threaded in the message list. In this case, "old" appears to be any that you have already looked at at least once. I assume this is designed to compact things, since otherwise sticky messages could easily take up an inordinate amount of space in the message list.
