Here’s a demonstration for you. Open TextEdit and save a file
to the desktop. Go to the desktop and move the file somewhere
else. Then go back to TextEdit, modify the file, and save it
Presto! New file on the desktop.
Do the same thing in BBEdit. No new file appears on the
desktop. Instead, the changes are made to the moved file.
Now, some of you are saying, “Ah ha, bug in TextEdit!” Others
of you are saying, “Ah, ha, weird behavior in BBEdit!”
