No history just turn to the previous or next page relative to the one you are currently viewing. When you use the TOC you are just opening the book at a new page. Back and Next are then relative to that new page.<br><br>The Connector pages introduced a different paradigm for the project. This paradigm required a historical back button. As an example consider a multiple choice connector page. Each of the answer options can link to a sequence of none connector pages, i.e. If the connector page is P1 then <br>option 1 may go to P2 which leads to P3 to P4 and P5 is a redirector page to P10<br>option 2 may go to P6 which leads to P7 to P8 and P9 is a redirector page to P10<br><br>The historical back is needed to ensure that if you traverse backward from P8 to P7 to P6 that the next backward action does not take you to P5 but to P1.<br><br>This inevitably clashes with the book paradigm when you use the TOC which is what Julian found. It will inevitably feel a little strange to Xerte users who are used to the book paradigm. However it does mirror the way a back button works in a web browser, so in a sense it will be what will be expected by anyone opening a Xerte project for the first time.<br><br>However browser users will be confused by the Xerte next button, as browsers that offer a next button base their next on the browser history. Such browsers (IE, Opera) appear to operate by building a history and maintaining a pointer as the history is navigated. Whenever a link is followed (rather than a back or next button) the "next" half of the history is deleted, so that on page exit the current page is added as the most recent page in the history.<o:p></o:p></p></div><div><p class=MsoNormal style='margin-left:72.0pt'><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-left:72.0pt'>If there are to be on offer in Xerte a choice between the original navigation or historic navigation then the historic navigation would be improved if it also was reflected in the operation of the next button.<o:p></o:p></p></div><div><p class=MsoNormal style='margin-left:72.0pt'><o:p> </o:p></p></div><div><p class=MsoNormal style='margin-left:72.0pt'>I have performed some tests in opera to figure out what is going on and have attached a pdf file to explain everything.
