Bugfix while displaying content of textarea-entered text (Strings with format=String.TEXT): for displaying again textarea content, I replaced 'backslash n' with html br tags, but in some cases carriage returns are stored as a sequence of 'backslah r' and 'backslah n' chars. In this case, 'backslash r' chars were left alone in the HTML page, producing sometimes strange behaviour within the browser.
