Thank you both, but the panel is not docking for me. It just hovers wherever I take it. It never docks, and it appears to the be the only panel in the Windows list that does that. When I select another panel like Text or Lumetri Scopes, the tab automatically appears in the Source Window with the other tabs. Also, any window I check off in the Windows menu stays checked, except for Properties. I have to keep checking it every time I want to open it and, as I said, it just hovers. I can’t dock it anywhere.
