Well, I kind of figured I could do something similar to what Dragan suggested before I even posted, but was thinking there was an API call designed for this. Anyway, I went ahead and implemented it using a Restart property on my application object. If Restart gets set to true - in this case due to a newer version of the program being downloaded - then the app does not finish loading and immediately before closing it uses ShellExecute to start itself again. This works. I thought I'd heard of a specific API for this type of thing, but maybe I was hallucinating.
