Post-reboot default font and background color settings inverted

now when i open LO writer and LO calc, all my docs open with inverted font/background color settings i dont use ex white font on black background - opposite to how it was before reboot.

so i need to find how to flip the switch to reset whatever setting got altered to return the app to the default background and font colors so all my documents present properly.

Still the same two choices:

  1. Backup the user profile, then reset user interface.

    Or less drastic
  2. Click Tools > Options > LibreOffice > Appearance and choose a theme, Office 2003 Blue is not too hard on the eyes but Light Application Color theme is a possibility although you want to change the setting Application background to Light Grey 3. Allow LibreOffice to restart
