[GNC] Could Not Obtain Lock

Mon Jun 27 06:08:40 EDT 2022

Might be time to upgrade to the latest version. This problem now does not exist
in V4.11 on Linux (Mint 20.3) and or Windows. You can close the app either from
the menu or by using the window close icon in the top RH of the window and the
lock is removed. A system restart with the app still open is still going to
leave the lock in place in which case you just select the Open Anyway on the
dialogue when it comes up. If you do upgrade check the wiki for instructions.
