When inserting e.g. a Fly In animation, I can still slide the Smooth start / Smooth end / Bounce end bars in the animation effect window, but when clicking OK to confirm there is no reaction. I can only leave the window by clicking Cancel.



Does anyone else have this problem or know what I'm doing wrong? Used to work just fine up to some time ago.

I have this problem with different presentations and on different computers.

Thanks in advance
