Well, I can't say that I've made much of any progress since the last posting. I took a 10-day trip to Israel to visit Bethlehem, Masada, Galilee, Jericho, Jerusalem -- all the holy sites. The trip was very intensive, and after I returned home it took me about a week to recover and then catch up on all my missed work.
I did spend a little time going over my test programs trying to figure out the right way to write Cocoa code for MacOS X document-based apps with Storyboards. What I'm doing seems too complicated.
So, I've decided I need to go back and find the WWDC videos regarding using storyboards with MacOS X, and it also might be useful to view the the ones for iOS docment-based apps as well, to see if that gives me any insight.
With any luck, I'll make much more progress in March.
