If you got the message saying that you're seeing the text-only version of a page, it means the stylesheet could not be loaded. Probably, your web browser does not support stylesheets properly, therefore what is being displayed is a format compatible with your browser version and your settings. To experience a better visualisation of the website, you should update your web browser.
Marine Software has validated the html code used and have extensively tested this website in the most popular browsers (Microsoft IE, Mozilla Firefox and Netscape included) in different versions. It's impossible to make all browsers display a complex site in the same way, but we had to assure you would be able to access all contents, no matter what browser or platform. If you're still experiencing any kind of problem, please contact us describing it and, if possible, telling us details like the operating system you are running and its version (e.g. Windows 98, Linux Ubuntu), the web browser you are using and its version (e.g. Internet Explorer 4, IE 5.1 for Mac), or you may even like to send screen shots picturing the problem you observed while loading the site. We would be glad and thankful and you would be helping us to be more accessible. Marine Software is always making their best efforts to please their customers.
