SV, I'm viewing your post on 5 different windows using 5 different browsers.
I'm afraid Netscape (4.7) is viewing full stops/periods as the only valid line breaks. It isn't wrapping the rest to selected window size.
Explorer, Omniweb, iCab and Opera all work fine. I'm keeping my sentences short. To help preserve your sanity.
As I can't find any normal user settings to stop this problem in Mozilla/Netscape. I'm afraid the short term solution is to search + download. One of the small footprint/high speed browsers such as Opera. A small file to download but a very good browser.
Our apologies for the problems - we are working to resolve the Netscape issue.
