Clickable, animated objects disappeared

After updating Storyline recently, a larger number of clickable objects have disappeared in many course files. The objects consisted of small round shapes including af text "i" for information. The objects had triggers that opened layers for additional information. Furthermore, the shapes had a mouse-over/hover state, that expanded the shape to a rectangular object including the text "click here for additional information". It seems like the animated expansion in the hover state doesn't work anymore and thus has erased all shapes and triggers. I have checked many older versions of the course file and the problem applies to all of them. I suspect that Storyline doen't allow animated states on e.g. shapes anymore. Is there anyone who has experienced the same problem or knows, what to do?
