It's not a question of how to get to the top of the post. Everyone surfs the net differently. Some of us use the back button a thousand times a day. It was just a question as to why it doesn't work as well on this site and I don't know the answer.
It's doubtful any of the other sites anyone visits are usng the same version of the Invision Powerboard as FiberglassRV. Then, think of all the different operating systems members of FiberglassRV are using. Unix, Mac (everything from Classic to Leopard), Windows
2000, XP, Vista, and 7. Too, the different browsers. The best we can hope for is to give people the solution:
Switch off "Show friendly HTTP errors messages
or provide alternate methods of navigation. As I said, I NEVER use the back button. That's my choice just as others have made theirs.
