again IMPOSSIBLE TO SAVE

[Emmanuel Companys]

Most of the difficulties disappeared when I delete all 1.1.1 files; but 
NOT ALL  of them!. The worst deals with saving and the file name.

1) I can save the stack I am working on, and even modify its name 
and/or label, BUT (for instance)
"put name of this stack" returns "Litteris 1.1.1 "
"put the long name of this stack"  returns "...desktop/Litteris 1.1 
o.rev"
and the actual name of the file on my desktop is still "Litteris 1.1 o" 
  (with no .rev)

This file opens my stack "Litteris 1.1.1 " that can be used, modified  
and saved all right.

2) If I try to modify the file name, I am back with the impossibility 
of saving and I end up with two icons: the previous one and a file 
labelled, for instance, "Litteris 1.1.1 .rev~" that won't open:  
leaving or removing the tilde I get the same "...Revolution has 
unexpectedly quitted" as soon as I click on it.

3) If I try to use the "SAVE AS..." item, I get the same result as in 
2.

Now my question is:
How can I have a file stack with the correct name?"
and, just to satisfy my curiosity:
- where this "" (radical, umlaut u) replacing the last character, 
comes from?
- why the saved file, when resavable, doesn't receive the .rev suffix 
as did the file of my stack "Polylexis" which never gave me any trouble?
