Summary: cannot reopen file easily

Initial Comment:
It is not possible to reopen a file in the editor if it is 
changed from outside. You will have to close the editor 
window and open the file again. Just open the file
in the editor will leave the contents unchanged.

Ah, yes, the /other/ editor.  Emacs, I presume, also my
/other/ editor.  Emacs has a rather sophisticated locking
feature involving symlinks which detects at the first
keystroke that another emacs has modified the file.
IDLE could interact with that implementation, but I
assume that you'd be satisfied if IDLE imitated the

 (if (buffer-modified-p buf)
 "File %s changed on disk.  Discard your edits? "
 "File %s changed on disk.  Reread from disk? ")

behavior when the disk file was modified by another
application. This would involve adding the equivalent
to (verify-visited-file-modtime buf) and an associated
EditorWindow modtime attribute.

When the file is saved IDLE could then also detect a time
mismatch and warn the user that he was about to overwrite
a modified file.

Hm, *I* would find it extremely useful. The other editor I
use a lot has several features relating to this issue, and I
*depend* on them.

This is an RFE which I believe would find limited use.

Calling an Open dialog on a file which is already open
merely wakes up the associated window.  Doing what
this RFE asks would require tracking the modification
times of open files and comparing upon re-open.
