Forum Software Upgraded

I though I did. I will try again.
When I click on the JPEG in the post of the link I provided for you, It does in fact open a window with a larger version of the pic. BUT, when I click the back button of that window, I do not go back one page to the post of the pic I clicked on. It goes back 2 pages to the page i previous visited before clicking on the pic.
So I just need to exit the picture. I guess the back button is actually doing what is supposed to do.
