The thing that stumps me is that the script works if run from the = scripts menu, it just doesn=E2=80=99t work when opened from the windows = menu.

I had a quick play yesterday and I changed the .value to = .valueAtTime(time, false).  The =E2=80=9Cfalse=E2=80=9D flag is = supposed to force the return of the expression and not the underlying = pre-expression value.  It still doesn=E2=80=99t work.  The = colour control that is applied by the script works as expected after the = script has run, so there=E2=80=99s no issue with the script applying the = effect and the expression.

I=E2=80=99ll try using a slider instead but I appreciate any other = suggestions...
