Here is an old problem I have noticed since BIAB for Mac 2013.
I have many songs with lyrics. I sing in aged care places and take a screen and project the words on to it for everyone to join in.(note based lyrics)
I have to use the windows version because it works perfectly - all the songs follow on with the words showing.
However the Mac version will drop the lyrics after a few 'next' inputs and the only way to re-apply the lyrics is to restart the Mac program.

Has anyone had this problem and if so how did you fix it?
If you don't know what I mean - try loading a song with words, then go 'next' song. If you then toggle between 'next' and 'previous' a few times and see what happens.
Cheers
