My observations have led me to the fact that the Virus Scanner is getting in the way. This is especially true after the updates to the virus db following the infamous "I LOVE YOU" vbs virus. You might want to look at an strace to see what happens with /usr/bin/echo within the Cygwin API's. Do `strace -o ./echo.strace /usr/bin/echo' then less echo.strace to page through the file. > Is CYGWIN=binmode supposed to be a global way of doing the same thing as > mounting everything in binmode because it isn't acting like it... ? > No, that controls the pipes and redirection and if your executing from a Non-Cygwin shell the stdio fd's. The default is binmode for these anyway.
