Thanks for your reply. I can see that it works in your example. But I was probably not clear. Your example is a logo that spins clockwise. What I'm trying to achieve is flipping (I think that is the correct word) the logo (I'm not a user of the English version of PP so I don't know the correct name of the animation).

Please see my example. You can see that after 15 seconds the logo disappears for a brief moment, reappears and starts flipping again. How can I prevent the logo from disappearing?
