I have version 6.0.16 on a MAc using OS10.7.5. Recently I noticed that if I edit text in a note, as soon as I type within a sentence the rest of the text to the right is highlighted, then deletes. This makes is virtually impossible to edit notes now! Also, if I do a hard return, I cannot reverse it with a delete key. My laptop Evernote 6.0.8 does not do this. Is this a known problem?
