Some consideration:


At 12 December: 

I work all day with the image.

at: 19:xx  I save the image without any problem.

But after saved the image the system begin 
unstable.

 
When the mouse go on the windows summary bar ( at the bottom of the Pharo window ) the image crash.

Some time i can launch - relaunch the same image from the PharoLauncher ( the pharo run but was unstable )

at: 19:45 After reload the unstable image ( as mentioned above )

i do the save command ( 
saving it on itself )
and the system crash.

After this crash ( when i do the image save command ),

i have not been able to launch the image. I do not know the status of this image ( I call this 
corrupt
image )

At 13 December:

A) 
From pharoLauncher i launch the corrupt image some time,

the  shell report the issue,
