Terminator closes when right clicked, unfocused (clicked outside of window) and so on

Some days ago I had the same problem. Even cleaning up terminator folder and resinstalling it, just doens't work...

Today, I noticed it was a configured behavement, written on terminator config file. So, you shold open it and clean 'focus' config line to let it default.

  1. Open terminator config file: ~/.config/terminator/config
  2. Check [global_config] lines, clean up any focus config line.
  3. Open Terminator; Click with right mouse button (even terminator window closes); Click in Preferences, On the new windows opened, in Global tab, check if Mouse Focus option is setted to Click to focus; Close preferences window.
  4. Open Terminator again and check if it's working fine!

A brief answer using GUI:

Right click to open "Preferences", and uncheck "Hide on lose focus" can solve this problem.

I noticed this after following the approach that @Mauricio provided.
