I have found a problem with Juicebox 1.3 in respect to Jquery 1.9. It could be that Juicebox is using a deprecated function
This is the error in Opera:

Unknown thread
Uncaught exception: TypeError: 'juicebox' is not a constructor
Error thrown at line 283, column 0 in <anonymous function>(e) in file://localhost/G:/My%20Webdevelopment/my%20webs/Afrika%20Website/visit_to_madagascar_antananarivo3.htm:

A workaround is to use the jQuery build of Juicebox. I don't know which one this is.
See http://afrika.delosgaia.nl/visit_to_mad … arivo2.htm for a page build in this way and without the error.
See http://afrika.delosgaia.nl/visit_to_mad … arivo3.htm for a page using jQuery 1.9, please check it with F12 in IE or firebug in Firefox
I have not tried the jQuery Migrate Plugin but it is possible that this plugin will also solve the problem.

The two named pages shall be removed within the next days.
