Mult Theme Problem With New Version

i recently had to go back to an older version of the plugin because it stopped working on secondary themes served by a multi-device theme switcher.(these would be mobile devices)

is there any coding you can think of that might have changed in the newest version so that it stopped activating on images in themes other than the main one?

is it possible the changelog that sayes it stops working if wp_mobile is true keeps it from working at all? or is it just supposed to disable the slideshow?

i can provide additional details.
