Yep. Having the same problem. And I just did what you said, Francois, and you’re right, closing the timelines allows you to right click on the video clips in the project panel. However, to extend the issue, whenever I drag the video files that I cannot right click into the timeline, everything freezes accept for keyboard shortcuts. I can save my project with the keyboard, but my mouse becomes absolutely useless inside of premiere. This is definitely a new bug from the most recent update of premiere. Francois, are you running Adobe Premiere Pro CC 2015.2? Just want to make sure it’s an update problem. I’ve never had this problem before.
