After OS 26 upgrade Calc files no longer open as previously configured. Instead the Libre Office splash screen flashes by. Then the default Open a file/application screen opens and closes, then my file opens in a reduced window. I then must resize the window to work with the file. Very annoying. Changes not retained. I must redo this every time. I’ve been useing L.O. calc for years. This behavior is new and correlates with Mac OS 26 upgrade. I can restore normal behavior temporarily by moving L.O. app to the trash and re-running the installer. But if I reboot my system the erroneous behavior returns. Bob Schmidt irontopp18@gmail.com
