title: Can't open in new tab in Sublime Text 3. Is it a bug?
body: <p>Today my Sublime 3083 became corrupted! I don't know why but every time I click on a file it opens on the same tab!
  I cannot open two tabs at the same time. Fist file opens in a new tab and another opens in the previous tab and so on!</p>
  
  <p>I did not installed any plugins recently. I just selected "Close Other Tabs" on menu.</p>
  
  <p>What can I do?</p>
  
  <p>Thanks</p>
