Update to Version 25.2.2.2

Have just upgraded to Ver 25.2.2.2 and I find that my documents have changed in appearance. Writer document and Calc spreadsheet now appear with white text on black background. Both items were black text on white background before upgrade.

How can I ensure that ALL my documents retain their original settings?

Many thanks.

Your documents did not change. If your operating system is in “dark mode”, LibreOffice adjusts to this viewing mode. The print preview (Ctrl+Shift+O) reveals, that your documents won’t print white on black.
Tools>Options>Appearance has 3 options “System”, “Light” and “Dark”.

Villeroy - Many thanks for your response to my query.

I checked the Tools>options>appearance and found the System setting was ‘dark’.
When I changed this to ‘light’ my query was resolved!

Thank you also for a very quick reply.
