Animated Graphic stops animating

[Mo Latin]

I have been trying out Xara 3D - great programme.

I create my first animated image and set it to loop the animation 99 times

If I go away from the web page I put it on and come back (before it could have done 99 loops) it seems to freeze, and refreshing the page does nothing to re-animate it.

It's here at [link removed] in the top right hand corner



What might be stopping the animation and how do I fix it?
