I found a thread telling me to use the Clone Effect under the Effect menu but I can't select anything in either Clone or Copy Effect. All options are greyed out. So, how do I use it? I've tried selecting the object, just the drop shadow and both the object and drop shadow together but I'm not given the option to copy or clone. BTW, I'm using X7.
One way is select the new object you want to set a drop shadow for and then hit this button. you'll get an arrow to select what shadow you want to copy, click on the shadow you already created.
