Apologies for truncated subject line due to char limits.
Sometimes when I change some object parameter e.g. XPos, a new keyframe is not automatically created on the Motion Tween timeline. Is there any reason\circumstance that causes this, or is it a bug?
Any help appreciated
I can't get mine to neglect adding a keyframe. I see no options for that behavior in Preferences, the object itself or anywhere in the ME panel and its context menu to disable automatic keyframing.
How heavy is the document you're editing? I used a brand new document and a new symbol so the stress was very low. Perhaps if the system is overburdeoned it's just not performing properly.
