Every time I click in the timeline to move the playhead, the playhead immediately goes to the end of the composition. If I click on an existing layer, it's starting point shoots to the end of the composition. When I right click on an existing layer, the drop down menu appears on my second screen. I have a dual monitor setup with 2 1920 X 1080 screens. I am running on a 2013 maxed-out Mac Pro. Anyone else having this problem?
