I started running BIAB on Powerbook Power PC using OS 10.3.9 w/no problems, then I upgraded to 10.5.4. Since then chord builder crashes as well as chord settings. I have made a few postings on this forum w/no definitive help. This seems like a software upgrade problem. I am pretty disappointed because I cannot use BIAD to change chord settings or create my own songs. If anyone has solid experience w/this issue and a fix I would greatly appreciate it.
