title: Right click mouse event bug
body: <p>I tried to fix a bug, for the last hour and I just couldnt.</p>
  
  <p>The bug is:</p>
  
  <p>If you press left click and dont release it, and then press right click (contextual menu appears) and then left click again, the first "drag" action is never released.</p>
  
  <p>Its like, I need to make that my right click says: "hey left click, your job is done, you can go home now".</p>
  
  <p>But I couldnt find a way.</p>
