next_post_link between archives

Once upon a time, back in 2.0 days you could calendar into my blogs, open an entry, then navigate anywhere with Previous Entry, Next Entry. This broke when I went to 2.1. It is still broken in 2.3.3

I thought it was my theme or the hacks I’ve made. However I have a completely stock install on another blog, and sure enough, the problem.

If I open a monthly archive, then a whole entry, I can previous/next through the month, but not into a different month. If I open a single post directly, nothing. This is what view source shows:

<div class=”navigation”>
<div class=”alignleft”></div>
<div class=”alignright”></div>
</div>

Is this working as designed?

Thanks,

Frank
