Your shell script is incorrect, and I don't see how it worked under 1.5. This line: > =C2=A0 =C2=A0 =C2=A0 =C2=A0set EXPLOR=3D'/cygdrive/c/windows/explorer.exe' does NOT set a variable named EXPLOR. Instead, it sets the first positional argument ($1) to the string "EXPLOR=3D/cygdrive/c/windows/explorer.exe". Whatever the old value of $1 was, it's now gone. To fix, get rid of the "set". In sh and derivatives, "set" sets the positional arguments (and optionally flags that affect the shell's behavior); it does NOT set variables. Just use the assignment syntax (var=3Dvalue) by itself for that. --=20 Mark J.
