I use the Inspector and Library as floating object on Mac OS X 10.10.2. Every time I load a project with 2015R1 the Inspector and the Library is not displayed. I have to enable it after loading the project.
When I create a new project, only the Library is displayed. The Inspector should I switch on.
With 2014R3.2 there were no problems. I think it only happens with the floating objects. Can anyone confirm this?
Another curios is, when I open the Preferences menu and close, then the Inspector is displayed.
