I upgrade to the latest Catalina beta and most of my non default buttons in all my Xojo apps stopped working! I documented the problem, created example apps, notarized them, prepared a post and… Tried restarting my machine. That fixed it.
You made my day, thanks for making me laugh.
Make sure you’ve added the code in your application to crash on a NSException (which can cause an application’s buttons, menu and everything to become unresponsive).
Thanks, Sam. Handy!
