This seems like a big problem that would affect a lot of people, so this may be a repeat, but I can't find the answer, so...
Using WP 2.3, when I post a future-dated entry with new tags or categories (that is, they haven't been used before on other posts) those tags or categories don't show up in the list of categories or the tag cloud even after the post's date has passed and it appears on the front page.
However, if I open the post in the edit screen on the backend and click "Save" everything shows up like it should. I really don't want to have to do that each time, though. :)
I've tried disabling all of my plugins and reverting back to the default theme, and the issue still shows up. Any help would be much appreciated.
