For the past week, whenever I double-click a text/textedit file to open it, unless I open Textedit manually before, it won't automatically open Textedit with the file. It does work if Textedit is already open, or if I drag the text file onto the Textedit icon, it opens (even when closed). But double-clicking as normal doesn't do anything. I get the open "zooming" animation, but textedit doesn't open. All other apps behave as they should. Can anyone help?
