Need script to remove the effects used in the layout for Indesign CS3 (mac version)

Here is a non-traditional approach

var action = app.menuActions.itemByID(67880)
if(action){
     var doc = app.activeDocument;
     for(var i=0; i<doc.spreads.length; i++){
          doc.select(doc.spreads.allPageItems,SelectionOptions.REPLACE_WITH);
          if(action.enabled){
               action.invoke();
          }
     }
}

id's don't usually change version to version.

It works on CS4, hopefully CS3 too.

AFAIK there's no simple command to clear all effects. You need to loop

through all the transparency effects and turn them all off...
