[SOLVED] I got fantastic support on this from Kirk Hunter AND the problem was my own misunderstanding - product in fact works as advertised.
Cannot get slur to work on Spotlight Strings
Spent hours... tried everything. Reinstall, etc.
Only thing that seems unusual to me is the install instructions say the result of the unzipped files should include folder named "Spotlight".
But don't have it, so it is clearly not included in download.
