Hi, I am new using eagle. I am trying to add a 0603 capacitor on the schematics in EAGLE. However, there is no ADD button as usual. I have turned on useall for the sparkfun library. Meanwhile, some of the components from the same library display the ADD button.

Can anyone help?

Thanks.

So which one is it? What ADD button are you talking about? The one on the left tool bar?
