This has got to be basic, but I haven't been able to find out how to undock the console or the tracks in the Main Screen view

Right-click on the console tab and choose undock If you are trying to use X3 like 8.5 it might be time to start learning how to use X3. Forcing X3 to work like 8.5 almost guarantees a tough transition. There are quite a few videos in CakeTv http://www.cakewalk.com/CakeTV/SONAR-University/Get-Started Learn how to use the docked Console with keyboard shortcuts "D" and SHIFT+D.

The quickest way to undock a view is to grab it's tab and pull it away from the dock. Presto! Free floating window.
 
What is frustrating is on a few occasions I'll open Console View and it appears in it's own window. When I try to dock it, it refuses to dock with no right-click options available. I can reopen the project another day and it will dock. So definitely a bug in there somewhere.
