title: Can't type in IntelliJ
body: <p>I'm using IntelliJ IDEA on my Mac to work on a project, and I keep on coming across an issue where I can't type. Occasionally when I switch to another application and then switch back to IntelliJ I can't type anything, and the cursor doesn't appear on text when I click on things. Does anyone know what causes this? After 1-2 minutes it goes back to normal, but it's started happening more frequently and it's pretty frustrating to not be able to type and have no way to fix it.</p>
  
  <p>This is the version of IntelliJ I'm using:</p>
