title: tSQLt.run does nothing in one Query window but works in another
body: <p>I have created 3 test classes.</p>
  <p>I can, from one query window run the following for all test classes.</p>
  <pre><code>tSQLt.Run 'class1';
  tSQLt.Run 'class2';
  tSQLt.run 'class3';
  </code></pre>
  <p>But from all other query window, the calls above simply don't work.</p>
  <p>So, to make sure I have a clean window, I put the focus on the query window where the calls work ... I hit CTRL+N to get a new windows, same user, same database, and I type <code>tSQLt.Run 'class1'</code>, hit F5 and the little green spinner with &quot;executing query&quot; is visible at the bottom and it looks like it will keep spinning for a long long time.</p>
  <p>Anyone available to help out on this.</p>
  <p>Regards,<br>
