Hello Andy,
here I quote from different contributions of the forum:
Spry was developed in 2006 long before touch screen devices. Spry has been dead since 2012. There's no point in trying to re-write the code to work in iPhones and iPads. Simply replace your Spry widgets with something better.
"Spry has been deprecated and is no longer officially supported by Adobe", “Adobe abandoned Spry late last year after CS6 came out. Future products will probably not contain any Spry so learning to use jQuery is a valuable skill to have for the future.” “The news was released in August 2012:
http://blogs.adobe.com/dreamweaver/2012/08/update-on-adobe-spry-framework-availability.html”
” and: "All Spry framework related examples available here: http://adobe.github.com/Spry/samples/
You may want to take a look at it. I'd recommend you switch to a jQuery library for your further requirements.
