Saving, when I click on "Don't save" !

[André.Bisseret]

Hello,
Since yesterday evening, when I am closing a stack (small red button  
top left), if I click on "don't save", the modifications I made are  
saved however  ! :-((

I spent hours trying to find what's happening, but without any success.

I suppose I have got a wrong inadvertent setting somewhere ??

Please, could someone help me ?

Thanks in advance

Best regards from Grenoble
André
