I went to settings -> Spell-Checker and I unchecked “Use automatic spell-checker” then pressed “Apply”. eM Client then switched to Italian. Underneath the check box, by “language” it says “Application Language” (which is English … how do I change that?). I tried changing that to the other options, including “English (United States)”, but that did nothing. I tried all other settings and combinations and I can’t get it out of Italian language.
I have Windows 10, 64-bit, and have just downloaded the new version (version 7.0.27943.0). I’m about ready to revert back to the old version that doesn’t have problems like these.
