I've recently started experiencing a weird problem with MS Word. When you select your entire Word document and change your language preferences, it should stay that way in that document, shouldn't it? That's been my past experience, but lately it keeps changing my preferences, while I'm still busy working on the document! For example, if I set it to UK English spelling and grammar, with the option to 'do not check spelling and grammar' NOT ticked, next time I look, it's again ticked to not check spelling and grammar, and sometimes the document is again in US English.
Does anyone know why Word would suddenly start doing this and how to fix it?
(I'm using Word 2010 and have not installed anything new recently, except for a Windows 10 upgrade a few months ago - the problem did not start immediately or soon after the upgrade, though; it's a more recent problem, as in the last few weeks.)
