In Euclid's spellcheck mode, if you right-click the misspelled word and correct it, the site does not autosave: you have to type something either in spellcheck mode or normal mode to trigger the autosave.
1. In any article where you know there is a misspelled word, while using the Euclid editor, switch to spellcheck mode. 2. Correct any misspelled words by using the 'right-click' and 'select' method. 3. no autosave is triggered until you actually type something.
