Hi Corinna,

Yes I am. And I did it again using the full path to the executable 
(c:/apps/cygwin being my Cygwin installation directory).

peugeot[/cygdrive/c/WINDOWS/system32]> c:/apps/cygwin/bin/cp notepad.exe 
notepad_copy.exe
peugeot[/cygdrive/c/WINDOWS/system32]> c:/apps/cygwin/bin/diff notepad.exe 
notepad_copy.exe
Files notepad.exe and notepad_copy.exe differ

Do you think it has to do with the fact that I installed Cygwin to use files 
in DOS mode (in one of the first tab of the Setup.exe application)?

Have you found anything suspect in my cygcheck log?

Vincent
