Keyboard is double typing the letter 'e'
Help! Suddenly my keyboard turns the letter 'e' into 'ee' and 'er' into 're'. I only seem to have this problem with the letter 'e'. I've checked my language and autocorrect settings but nothing seems to work. I have online exams next week so this needs to be fixed asap :(
Thanks in advance.
