To say I’m disappointed with Xertes 2 is an understatement 🙁 It used to be up-front accessible – you could change the text size, colour, background etc to suit your own requirements. 
Xertes 2 has lost this. I’ve been told this is now html5 rather than Flash but the Tooltip function on the images isn’t working – not is the magnifier – at least, not in Chrome and I haven’t seen any browser preference specified. whether I select Default, Full Screen, or Fit Window, the size remains 800 x 600 – unless I alter the Embed Code (see second example). I may need to experiment more with sizing when creating content – I worry this is another example of the invisibility of digital divides and prevalence of the tripartite MEE Model of computer access; Mouse, Eyes, Ears. Accessibility features need to be visible and at first sight this looks like a loss rather than gain.
