Save changes before Opening ->Yes ->> Open File

[Burdy]

If you change a file, and before saving it
try to open another file, you are given the
option of saving the changes.  If you choose
Yes, you get a file Open dialog which
actually saves the file when you
choose 'open'.

It does do the save but its kind of scary to
save a file by clicking open.  This is on
