"horizontal spread" problems?

[ladyinthemists]

I have members saying that they are having problems with the horizontal spread on my forum site. They tell me that when they adjust their resolution settings on Windows, it makes the forum appearance almost OK, but ruins all of their other settings. I cannot see any problems on my own computer so I am not really certain as to what they mean. What can the problem be and how can I resolve it for them? My site address is: http://gosc.s1.bizhat.com/

I am STILL having complaints from my site members saying that the pages in my forum site are too wide and they are having to scroll from left to right to see the whole page. How can I fix this problem? My site is located at: http://gosc.s1.bizhat.com/

Thanks

Okay, I have now suggested to my site members that they adjust the screen resolution on their home monitors to hopefully correct this problem. One of them tried it and said that it made the text too small to read. Isn't there anyone out there who can help me out with a viable solution to this problem??? Please!!!
