Hi Valeri

I did that in the following and there's no loss of files.

1. edit one file. e.g. oo.C in the first console
2. open the same file in the 2nd console, I got the following message from vi as attached.
3. neglect the message and hit return, then one will open the same file in two different consoles.
4. go back to the first console and make some changes and save it.
5. go to the 2nd console and quite the vi
6. check the file and it's still in the directory with the changes made.

Note that as I mentioned before, when using ROOT, the file w/o the function name does NOT have the problem, e.g.

   {

       cout<<" hello"<<endl;
   }

But the file has the function name has the problem, e.g.

    void oo()
    {
      cout<<" hello"<<endl;
    }

This difference does not appear in above exercises. So I feel it does related to ROOT.

This is not a serious problem anyway.

Cheers

E325: ATTENTION
Found a swap file by the name ".oo.C.swp"
          owned by: wxie   dated: Wed Jul  1 17:51:34 2009
         file name: ~wxie/oo.C
          modified: no
         user name: wxie   host name: D2SLGPD1
        process ID: 3304 (still running)
While opening file "oo.C"

(1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r oo.C"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".oo.C.swp"
    to avoid this message.

Swap file ".oo.C.swp" already exists!
