Why not use cygstart to launch it already "detached"?

You might create the following alias in your profile or .bashrc.

alias notepad=3D"cygstart '$(cygpath -u -W)/notepad.exe'"

But if you do not want to be limited file in the current working
directory, use a function.

notepad ()
{
    cygstart "$(cygpath -u -W)/notepad.exe" "$(cygpath -w "$1")"
}

You might have to change -W to -S in the first cygpath, if notepad.exe
is in $SYSDIR but not WINDIR.  (In my instance of XP, it is in both.)

Best wishes,

- Barry
