I don't know why this is suddenly happening, but on both Mac and PC, when I try to move tabs between panels, they don't leave the panel. I hope I'm using the correct terminology. Like I want to move the Text tab to the same panel that the Source tab is on, and when I drag it over, it refuses to leave it's panel. I've never had this happen in the 10 years of using Premiere, and it just suddenly started happening. I hope this is a bug and not a new "feature". I literally cannot move AN Y tabs outside of their panel. Any ideas what's going on?
