I also noticed that the executable doesn't show up in File Buddy, unless you use the Finder, then highlight the executable, then select File Buddy from inside the Finder. When I do that, I see that the Spark LE executable is actually a folder of some kind (a "package"?).
I've looked through the meager Mac documentation, and tried the mac.com site. I've also spent a couple of hours browsing via search engine without success.
Yes, I'm a Mac newbie. HELP!
