I've just bought a new laptop a Dell Precision M3800 with 16GB RAM, running Windows 10 Professional. I've installed Neck Diagrams 1.12.0, and successfully copied my data from my old laptop.

Everything's working except the inspector, which never appears. Nothing works, whether it's the Show Inspector menu option, or the Control-I shortcut, or the Inspector toolbar button. This is a showstopper, as I can't now create new diagrams, or edit old ones.

How can this be fixed? preferably without reinstalling, as that took me long enough the first time. Thanks in advance.
