This began a couple of hours ago. The session was going fine, I decided to rearrange some tracks into folders, and suddenly my playhead stopped responding to the spacebar or manually clicking the transport. Either way, the transport button blinks twice, then... nothing. Frozen. I searched thoroughly and tried every solution I could dig up—such as the notorious "Link timeline and edit selection" issue, etc—finally trashing my prefs (which I really don't like doing), and got it working again. Just now, continuing my work, I created a new stereo aux track—nothing more than that—and the playhead's stuck again.

Whatever this is, it's global. Testing shows it's stuck on any session I open. Not doing anything different than usual. My CPU usage is topping at 40%, so I'm good there. I really need to get back to work.

Thanks.
