If the page doesn't wrap in Internet Explorer then it is due to the settings you have on your PC. If the page doesn't wrap in Netscape then you need to upgrade to the latest version which does not have the problem.
I have tested these bulletin boards using Explorer and Netscape (latest versions) using a PC and using Explorer, Netscape, Opera and iCab using a Mac and there were no word wrap problems.
If you get a nowrap page occasionally on only the odd thread then it is because the poster has included a very long line of text with no breaks, such as a long URL. In such cases all browsers will be messed up. Blame the poster. This new software should prevent that happening but it is not infalliable.
Do not let Microsoft dictate how you should enjoy your internet experience. Get a life... get a Mac!
