Overnight the headings in my eM Client have converted from English to a foreign language. Messages are still in English. How did this happen and how do I fix it?
Problem resolved. Closed client and rebooted and now we’re back to English. Weird!
Maybe emClient simply wanted to show that it can speak foreign languages, too.
To be serious: In Settings → Language you can change the program interface language. Maybe there is a hidden accidentally pressed keyboard shortcut for changing the language ? (No clue – windows has sometimes its »special moments«) – reboot is always a good idea as first attempt. Solves > 95% of problems.
