A website created under version 16 of Designer ProX has pages with layers so the mouse hovering over particular locations will reveal an additional image. This works on the exported website and in the web page preview. If I open the same .xar file in version 17 neither the preview nor export shows these pop-ups. Interestingly, editing other pages under version 17 and opening the new .xar file under version 16 the desired effects are still shown in both preview and upon export. Am I missing something obvious? Happy to provide the .xar file if that would help (the published website can be seen at uhulmc.org and the pages in questions are those accessed via the menu Miglia Quadrato --> More Questions and Answers or Londinium Pedo --> Questions and Answers

Any help gratefully received.
