Sometimes I get playbacks that weirdly "image freezes" (plays but doesn't show image) on the transition clip (transitioning to a still image). It looks ok when I scrub and export though. Why does this happen and how do I fix. v7.3
*edit* Weirdly, it plays back ok when I insert a video track below my still images.
*edit 2* Frustratingly, when I close the project and reload it, I get a blank black screen on playback.
