Alt-layouts in latest release 4.18.0.0400 caused crash on Mac when navigating to item with different layout set up (in my case a song with lower 3rds for stream. Also other items with alt-layout set to picture-in-picture reverted to slide. I ended up downgrading to 4.18.0.0365 to get back to a working version. My Mac is just a prep computer; our production computer is Windows. I will avoid updates until I see improvement.

  1. On a separate note, how do I keep updates from automatically loading on my Mac? I just had to downgrade again as quitting Proclaim caused the already-downloaded update to install!

  2. I'll be downgrading every time I need to open.

  3. 4.18.0.0401 fixed it
