Ok, so I created two custom NSToolbarItems, that I'm using regularly in a number of apps. To make it easier, I copied them into the library in IB so that I can just drag them onto my interface every time I need them. Unfortunately, when I copied them into the IB Library, it apparently didn't take the icons with them, so I still have to find the picture files and add them to my project, every time I use them. Is this normal, or did I do something wrong in the copying to the library?
