When I edit an original text for the first time in Whiteboard and then save a new version it does not stay within the limits of the text box, but spills out all over the whole page. So the newest version and all that follow have lines running over the hyperlinks to my other pages, all over the coloured background and becomes impossible to read and to edit again. What is happening? I use Safari as my browser, but have also tried Firefox and the same thing happens . . .
