If multiple songs use the same PDF, and you want to replace it with a new version, you can use the swap file feature on one of those songs and it will replace the file for all of them (so long as the file name doesn't change). This is equivalent to just replacing the file on disk, which it sounds like you did.

As far as you losing your patience, I'm not sure what alternative you would like for obtaining answers to questions. I respond to emails pretty quickly, but the forum posts also benefit other users who may have the same questions. I plan on improving the manual and providing a web-based solution that will hopefully make it easier to look up answers to specific questions, but I don't really have the bandwidth for that until I complete other work.

Thanks, Mike. Please know, however, that the current manual does not say what you just did and I tried to rely on the manual before bothering you (or anyone else) on the Forum.  You are indeed extremely responsive to questions and I appreciate that. My only criticism is that I've had to ask more questions about the functioning of this application than with any of the hundreds of Windows applications I've used over almost 40 years.
