  According to PN API docs pnBlockShow is supposed to return the output of the block display function.
  
  I have seen in other posts the suggested usage:
  

  Code

  echo pnBlockShow($module,$row['bkey'],$row);

  
  This works but not for the right reason. Most (all?) of the time pnShowBlock echoes the output and returns nothing.
  
  In pnRender's function.pnblockshow.php the following code
  

  Code

  ob_start();
              pnBlockShow($module, $blockname, pnBlockGetInfo($block));
              $output = ob_get_contents();
              ob_end_clean();

  
  clearly indicates the output is expected to be echoed, not returned.
  
  My question: Are there any conditions that cause this function to return the output as opposed to echoing the output?
