playhead jumps to end of timeline
In FCPX (10.15.3), I have suddenly discovered that I can't press play (either using the space bar or the on-screen button) without the playhead jumping to the end of the timeline. It happens on all projects. Doesn't seem many, if any, people have had this problem and I've been using this version of FCP for some time now. Please help!
