I wonder if I'm doing something wrong or if there's a bug or something. I just finished up a project, rendered it out, saved, everything was good. Now I opened it again a couple days later and I can't drag any clips around, I can't even drag a new clip anywhere from the Project Media panel. I also can not drag any Effects onto the timeline. I can select things and even delete clips, just no dragging. Is there something I can do here?
