I've been interested in learning Cocoa for some time, so I decided to download Apple's "Developing Cocoa Objective-C Applications: A Tutorial".
I believe I have followed all the steps correctly in creating the CurrencyConverter window in InterfaceBuilder. For whatever reason, though, my "Convert" button doesn't have a "target" outlet (only formatter, menu, and nextKeyView), so I can't connect it to my ConverterController instance.
Have I missed a step or something obvious, or is there something wrong with my installation of the developer tools?
