I sent a tech support report on this several weeks ago, but never saw a response:
OS:8.1
App: 4.0.8
* From the full screen screen lyrics/performance screen, I tap EDIT to edit the song.
* The song edit screen appears, split with the show song list on the left
* I make any changes to the lyrics, recording, midi or whatever, OK
* I then tap on another song on the list to save the edit
* At this point SLM freezes, and I have to exit and close the app. Sometimes, if I wait long enough, SLM will crash completely, but I usually don't wait.
When I open SLM, anything I had changed is there, so it is saving what I did. If make the changes back in the SONGS option of the database, there is no problem.
Here's the reply I sent you on October 16:
"I noticed that in the 4.0.8 beta and fixed it before submitting the real release. So that problem should go away if you download the real release after it appears in the App Store."
I don't have that for some reason... anyway, the new beta fixed it. Thanks Arlo!
