I posted pics above which I believe answered your question unless I am not understanding you.
Sorry about being so anal about this. Here are the steps I take.
1) Post reply (to another thread)
2) Reply to thread box (in blue) comes up
3) Title: and Message: boxes
4) Type in box (like I am doing now)
5) Click on "submit reply"
6) This brings me back to the thread, with my new on added.
7) Then I go to "New post". This brings me all the way back to page one. Say for instnace the post I might of replied to was on page 8.
What would be the next step to get to page 9 without having to go all the way back to the beginning of the post?
