When I try to select a clip to move it left or right along the timeline the clip highlights but the curser turns to the hand tool grabbing the clip and then there is a small circle with a dash through it. It won’t let me move the clip on the timeline at all. If I grab an effect from the effects window and drag it to a clip the same thing happens. When I grab an audio clip, it lets move the clip downwards creating a new audio track but then I can’t move it back upwards. The audio clip will move left and right along the timeline but creates a new audio track each time in the process. So If I move the audio clips to the right it will move but creates and moves to a track 4. Then if I want to move the audio track back it will move back but then creates an audio track 5 and I can no longer move it to tracks 1-4.
