When selecting the URL you will use for the link try to avoid the ones that say new or part 1, all numbers seem to work better.
It helps me to get a proper link by clicking on the red name in the shaded portion of the next post. So if you click on the Re:Cadet in this post it will give you the link for the previous post.
When it is the first post of the thread sometimes I will use the "View Posts" function to get me the proper link.
Lot of work to get the right link but it is worth it!
