I'm not sure what you're referring to. We haven't changed any settings on the forums that would cause it to be wider.
I'm guessing you accidentally zoomed in a little bit which makes the page looks bigger. Press "CTRL+0" (zero) and it will reset your zoom setting. If that doesn't work, let me know.
Thanks guys I must have zoomed to 150% . I think now I like it better at that size . Lot of web sites have zinc side pop ups . All my others didn't change and I didn't relize zoom was site specific .
I do notice that the pages do not automatically size to the screen. I can't remember if they did before. It does not matter though since it is the ads on the right side that are being cut off and not any of the forum.
