Captivate 7 - Millenium Interaction - iPAD issue

I have inserted the Millenium Interaction on a slide and have 12 questions.  Apart from setting the questions and amending the Hint for each question, I have made no other amendments to the Interaction.  When I play the project on a desktop (Flash) it works fine but when I play through an iPAD, when I select an answer, the iPAD Keyboard appears on screen.

Any ideas how to fix this ?
