Steps to reproduce the issue:
Step 1: Open a fully processed project file;
Step 2: Go to DF3.1 and select the DIAM table, so that it is opened in the workspace area;
Step 3: Now click with your mouse twice on an icon on "Special"-toolbar for example the "Show minima"-button. You will see that the toolbar has been activated fully. You can check the table again, and so on. Other toolbar are also activated.
