Hi sd_garrett,
Thanks for your reply.
I just gave another go, now i can get the controls working on iPad with your solution, regardless of publishing the project into SCORM package(either SCORM 1.2 or 2004) or just noraml HTML5 outpout with SCORM disabled. However, I still can't manage to get this work on PC with html5 supported browsers, any idea why it is not working on PC? The master slide of my test CP project actually didn't contain any object, it is literally just a white background.
Cheers,
Amy
