Baron I think you are correct. Testing some more tonite I confirmed I have to hit the back arrow on the browser OR back button on my mouse 4 seperate times to back up one step on the forums. Although right clicking on the back arrow like you mentioed only gave me the option to minimize/max/close etc, I notice a small looking down arrow that does what you described showing the recent pages visited.
So for example, lets say I am in the General Discussion main page, then I click on a specific post to read, after that page is loaded and I click on the down arrow it show 3 seperate lines of googleads.g.doublenet/page and then on the forth line I see the discussion forums main page. This explains why I have to hit the back arrow 4 times to go back one step. Also if I click on any of the google ads lines nothing happens. This also explains why nothing happens when I hit the back button 3 times, until I hit it that 4th time.
So by doing the down arrow and then picking the 4th line down i can back up 1 step. It's easier than hitting the back button 4 seperate times, but still is not what I consider user friendly. I know it's not the site, it's my browser, but this is the only site that causes me this issue.
For the hec of it I tried this site on a computer at work and the back works fine with just one click, but I can't use the work computer for surfing the net.
Maybe there is something in my browser settings I could do to prevent this issue, but I have no idea and if I have learned one thing about computers, it's that I shouldn't mess around when I don't know what I'm doing or I will just create bigger problems. LOL
