I'm making a Flash animation in Flash CS4, using motion tweens to change positions and sizes of objects on stage. I frequently open the animation file and find a motion-tweened object has been moved to a new position from the one it was in when I last saved the file. All the frames in the tween seem to be affected. If I open the file again without saving, the object is still in the wrong position. I have had to redo or substantially correct a big tween several times. It's wasting time, and I can't rely on my work being in the state that I saved it last. I think the problem happens to the files when I open them after starting up Flash.
Does anybody have any idea what could be happening, and how to stop it?
Sorry, forgot details: I'm using Flash on Window XP Home ed. My version is Flash CS4 version 10.0.2.
I'm having the same problem. Thought I was the only one.
