Hi -
I was having this same problem, which I did not experience with the old Forum. What Cathe's Administrator recommended to me and it works is go into your Properties (right click on main screen, scroll to Properties).
Once there go to Settings and make sure your pixel image is at 1024 x 768. This makes the font much smaller (and hard for these 49-year old eyes to read!), but it does shrink the Forum text onto the screen so you wil not have to scroll back and forth.
Once I am done reading Cathe Forums, I go back to my larger pixel setting. Kind of a pain, but it works.
