It happens to all of us- the accidental close of a compose window by
clicking the wrong one, pressing the key combination to the wrong window,
or so on.  People put a lot of work into messages.

This simple addition prevents that:

imp/templates/compose/compose.js

I added this just above the 'function confirmCancel()' at the top of the
file within the script tags.  In theory, it could go anywhere.
------------
window.onbeforeunload = bunload;
function bunload(){
        dontleave="Are you sure you want to close this window?  Closing
this window will discard any unsaved changes.";
        return dontleave;
}
-------------

This will prompt the user upon closure.  I have tested this on FireFox and
Internet Explorer.

A small addition, but an important one.
