I just used the backup function again after a long time and found the text being cut off in german (seen here). Maybe this is due to Win 10 (or me) using other scaling settings. The text is displayed as tooltip when I hover over it, but this is not obvious to all users.
Is it possible to add automatic word wrap or maybe a defined line break? I could try some other phrasing, but that would alter the meaning a little bit (something like "Don't close the output window or the prozess will be terminated").
