I've been reading Cocoa Programming for Mac OS X and have been finding it enjoyable thus far. The challenge at the end of chapter 5 has been giving me fits however. I just can't make it work. I've looked around online and it seems that everyone else's solutions are exactly what I'm doing but for some reason I can not get it to work. here's a site that describes exactly how I tried to solve the problem but when I run the compiled application it does not work! I'm thinking that perhaps it could have something to do with the book's teaching of 10.3 instead of 10.4 but I've seen other people saying they were programming in 10.4 I'm trying to get this to work before I move on to chapter 6. Any help would be greatly appreciated!
