I have found roughly 176,973 supposed solutions on the interweb to the problem of MS Word constantly switching back to a U.S. dictionary despite selecting the UK as default, but none worked. Help?! And how come the spellcheck regularly fails to pick up on incorrectly spelt words? Even if I typed in Tfhsfajliqgdadjkagd it would pass it as okay. (Maybe it's a city in Uzbekistan?). Help?!
