I think I can say with certainty that many geeks have the Bad habit to click on the screen, or type letters randomly, and with the eyes or the mind is devoted to another. How many times, as if by chance, we went to finish with the pointer on the red 'x' shown in the upper right on the windows and we clicked! Rarely are affected applications, but we put the case...
If the defect persists and is likely to send up so much work in smoke for such nonsense, we can resort to a trick (pending correction of the defect, ndr) to avoid damage particularly relevant: save, certainly, but also disable the Close button to NoClose application.
This freely downloadable program, does not require any installation. After being launched, the program provides a hotkey to bear in mind for attribute / disable button Close the active window: Ctrl+1 or Ctrl+2, to create a new rule. Additional settings in the Settings (right click on the NoClose in system tray).

To all of you a good navigation...
