title: setbkcolor() ineffective in Dev-C++ 4.9.9.2
body: <p>I recently started using Dev C++ 4.9.9.2 to experiment with graphics program in C(thanks to this <a href="http://www.cs.colorado.edu/~main/bgi/dev-c++/" rel="nofollow noreferrer">tutorial</a>). But for some reason <a href="http://www.cs.colorado.edu/~main/bgi/doc/setbkcolor.html" rel="nofollow noreferrer">setbkcolor()</a> does absolutely nothing. Here's the code...  </p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;graphics.h&gt;
  #include &lt;conio.h&gt;
  
  int main()
  {
      initwindow(800,600);
      setbkcolor(GREEN);   //FAILED. also tried "setbkcolor(2);"
      while ( !kbhit() ){}
      return 0;
  }
  </code></pre>
  
  <p>Here's the Output: <a href="https://i.stack.imgur.com/ItkxB.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ItkxB.jpg" alt="black colored screen still"></a></p>
  
  <p>I am using <strong>Windows 7 Professional</strong>. Is this something to do with the Operating System?</p>
