About Dialog
Check which version of Cygnus you have and whether it is licensed or in trial. Open the About Dialog from the Help menu, read the version and license status, and click Close when you are done.
The About Dialog is a small window that shows the Cygnus icon and name, the Version, the license Status and the copyright notice. It opens over the main window, and the main window is usable again once you close the dialog.

On macOS, the Help menu is in the menu bar at the top of the screen. On Windows, it is in the menu bar of the Cygnus window.
