I undocked the Event List, System Console and Local Variables so I could see more content. Then when I tried to "re-dock" them they appear in a "sub-window" as shown:
Debug windows undocked fs22.1.2.fsm
I then tried again to move them into the "main" console, but then the whole console disappeared, and I can no longer open any of those consoles from the debug menu.
Debug windows disappeared fs22.1.2.fsm
Fortunately I was able to reopen the undocked version of the model and then close the windows using the red x, and then when I reopened them they were in the right place. So I can continue from there, but wanted to show you this behavior so that you can fix it!
Thanks.
