Thanks, resolved!
Thank you and you are absolutely correct!
I had ordered the Belkin (it was back-ordered), before I installed the Zagg. After gettting the Zagg on, I became worried and was considering canceling the Belkin. Meanwhile, the Belkin ships and arrives in 1 day! I had to try it anyway, so can now say first-hand that they do NOT work together and back it goes.
