Well, I tested the forums even with 640X480 pixels, and the layout adjusted right to fit in the screen, showing the table completely without necessity of scrolling. Probably you're having problems loading the pictures of the icons, that could cause the layout of the forums to look "out of bounds".
I don't know how to help.
Make a screenshot of your desktop and attach it to your next post:
---press PrintScreen
---Go to Paint and select Edit, Paste
---Save as JPEG (so that the picture file doesn't become to big)
---attach it to your next post
At least this way we will have an idea of what it is happening.
