I have been working with after effects for many years. All of a sudden whenever I add a keyframe, scale anything, add an effect, move the playhead or literally do anything, After Effects gives me the Refresh Disabled (release Caps Lock to refresh view) warning. My caps lock is definitely off. I have to press the caps lock button two times to be able to see what I am doing. This is awful.
Any one have any ideas? At the moment After Effects is unusable.
