Interactive Video

Interactive Video wont scroll through playback

I have made 3 interactive videos. The first video worked fine, although the second two wont allow me to scroll through the playback bar while editing or when I create the video. It goes back to the start of the video. Its like the scrolling feature to prevent scrolling has been ticked but its definetly not ticked. Has anyone else had this issue before? Its quite hard to edit when I cant scroll.
