Known issues
- 
When using multiple screens, if you move the application to a secondary screen, and later switch to using only the primary screen, the GUI will open off-screen. The remedy is to delete the preferences.jsonfile created by the application before running the application again.
- 
If you minimize the Help Window and then run the helpcommand (or use theHelpmenu, or the keyboard shortcutF1) again, the original Help Window will remain minimized, and no new Help Window will appear. The remedy is to manually restore the minimized Help Window.
