We are investigating a new crash that can occur when Hook is idle. A customer kindly reported this, and I have managed to reproduce it.
I suspect it was introduced in build 2014 released today.
Here is the prior build (2002) if you want to roll back: https://dl.devmate.com/com.cogsciapps.hook/2002/1549943498/Hook-2002.dmg . We are not yet recommending a roll back, but obviously if it’s frequent you may wish to consider doing that.
