I also have the problem when adding authors to songs. Also, when importing from a CCLI SongSelect file it adds the author with a space in front of the name, even if the autor is already in the database. Mac OS X 10.6.8.
I've been using the Mas OS X version and it works pretty good. You may get some error messages and I've had an issue with the font size getting small a couple of times, just restarted the program and the font size is back to normal.
Perhaps in a future release the user can select were to store the song, theme, and other databases. This could include a network location. A problem could be working offline.
Don't see it as a huge isue now. Just wanted to make sure that the update worked right. It would be nice if the version number was changed on future versions. Thanks for all your hard work!
