I have noticed the same thing. I access these forums from several different computers with different screen resolutions, and it is happening on all of them. I think it is a problem with the "wrapping" function, since it happens at every resolution and when printing. Another clue is that there is no horizontal scroll bar as there should be if the web pages were intended to be wider than the browser width.
I hope they fix it soon. Some of those words I can't see over to the right might actually be important.
