I guess it's just me, but every time an animation plays, the view freezes on the last frame of the animation. If it's in a scene and there's more dialog after, then if I click a few times and scroll back the view returns. I almost got stuck after the walk in the park because the animation was the last thing in the scene, and stayed on the black end frame of the animation.
The workaround is to right click to get to the save screen, then hit escape. Hope this helps if anyone else is having this issue.
