If Amphetamine is not working properly, a common solution is to reset Amphetamine's preferences. 


Note that deleting Amphetamine's preferences will result in a complete reset of the application. 

This means you will lose all Triggers, custom icons, custom default durations, and all other configuration. 

Amphetamine will be reset to a default state.
