this one is strange. all of a sudden when I click on a position keyframe in a 3D layer it moves exponentially faster than I'm moving the mouse. The keyframe will quickly move out of the window. Even stranger... I cannot undo this. Undo does nothing. Lastly, when I hold down Option and move the keyframe, it works as expected. Any clues?
yeah, it's gotta be that since holding down a key turns it off. Nothing is physically stuck, but clearly AE thinks the key is down. Funny, it's only THIS project where it happens. I open another AE project and it's fine.
