The first message in a forum seems to display fine, but all of the replies are stuck underneath in a narrow column on the right. Might be my browser. Seemed to start in the last day or so. Does anyone else notice anything unusual about the display?
Just out of curiosity, what browser and operating system are your using? I have tested it on the latest version of Internet Explorer and Firefox on a pc and it looked fine.... I am wondering if you may be on a mac?
