« Previous Thread | Next Thread » missing when forums sorted alphabetically

[user-1231235234532]

For various forums we have set the sorting to "thread title" (using the admin panel) to make sure they are listed alphabetically.

As a result we have no "« Previous Thread | Next Thread » " links at the bottom of the threads in these forums.

Is this an imperfection , something wrong with our install , or is there a good reason for this ?

The code the looks for the next/previous threads looks based on the date/time the thread was posted and only that, so it must be disabled when anything except the default sort is chosen.
