The credit for this program's continued compatibility is due more to Apple than to myself. All I did was choose Cocoa Java and Applescript, both of which just take advantage of fast, stable underlying code regardless (so far) of the OS version (or these days, underlying hardware). I wonder if Cocoa Java apps qualify for "Universal Binary" status... :)
Look for a new version in the next couple of months (whenever I get a new machine and bother to move the project to XCode) with a lower-profile UI and some new features (hopefully including the fine suggestion from 'quite').
Thanks again for your feedback-
