WinVN currently uses the standard Windows edit object and puts both headers (labels that the News Server uses) and text into it. If autowrap is turned on, it effects both the text and the headers. This is good for the text, but very bad for long headers. For this reason, WinVN currently does not use word wrap. Given that this is a commonly asked for feature it will be added in the future. However, it requires some significant coding to be done. So, be patient and it will come.
