Every so often, I will be doing something on my computer (e.g., in Google Chrome), when an alert dialog from TextEdit.app randomly pops up. The dialog looks like this:
The dialog asks if I want to save changes made to an open or minimized RTF document in TextEdit. The dialog sometimes appears even when TextEdit is not the active application; the dialog comes out of nowhere.
My answer to this dialog, 100% of the time, is Save Anyway. This is because hitting the Revert button irrevocably changes the file to the last-saved version of the file (which is obviously undesirable).
If the document is not being edited in another application, then why does this message appear? Or, how can I figure out which application (i.e., "another application") is responsible for the changes to the document, exactly?
Is it possible to prevent this dialog from needlessly appearing? Or, is it possible for Textedit to "save anyway," by default?
