Problems with input
My keyboard works perfectly well with Word or Notepad, but in Duolingo I cannot put accents on vowels. Choosing an accented vowel with the mouse however works. I'm I the only one with that problem?
Here's a (competing) Spanish-learning site that explains this issue well at this link:
In short, set up the U.S. International keyboard as an option. Then, one can type the special Spanish characters with two-letter sequences, like tilde then n for the ñ, but type a tilde followed by a space to insert an actual tilde (~). Hope this helps.
