v10.10 beta last post

I found another thing that bugs me but can't really figure out what's wrong.

The last topic list (from main forum page) doesn't work as expected for all topics. When clicking a topic, most of the time the visitor is pointed to the last post which is ok. However, some links do not work correctly since the first post is opened (not the last one).

Tried this forum and found the same thing with the following link for example (from the last post list )

Ups ... 
Thanks !

In our case it doesn't work for all links. For some it does work as you described in other doesn't and i can't figure out the patter of the problem.
But, i found what "fixes" the issue (all links do point to the last post .. since this is what we are used to have)
We do have url rewrite enabled (and i updated to the newest version) but if i change the code from

If blnUrlRewrite Then
                Response.Write("<a href=""" & SeoUrlTitle(strSubject, "") & "_topic" & lngTopicID & ".html" & strQsSID1 & "#" & lngMessageID & """ title=""" & strMessage & """>")
            Else
                Response.Write("<a href=""forum_posts.asp?TID=" & lngTopicID & "&PID=" & lngMessageID & strQsSID2 & SeoUrlTitle(strSubject, "&title=") & "#" & lngMessageID & """ title=""" & strMessage & """>")
            End If

to just

Response.Write("<a href=""forum_posts.asp?TID=" & lngTopicID & "&PID=" & lngMessageID & strQsSID2 & SeoUrlTitle(strSubject, "&title=") & "#" & lngMessageID & """ title=""" & strMessage & """>")

Then it is working as we are used to.

Mind you that i'm not an expert in these things and i pretty much work on try and error base :(
