title: Apache NetBeans 11.1 not working correctly
body: <p>I'm using NetBeans 11.1 on Windows 10.</p>
  
  <p>It has been working properly for the past year as it should but for some reason now I cannot copy/paste text, the 'undo' action isn't working, it cannot automatically highlight any variables that are the same in the class, it just seems that its not working at all. </p>
  
  <p>I've tried restarting it, restarting my PC and reinstalling the program but it hasn't helped at all. Reinstalling it kept my last configuration settings so maybe I should reset all the setting but I don't know how to do it. Can you help me?</p>
