MAYA ERRORS: // Error: setParent: Object 'renderView' not found.

// Error: setParent: Object 'renderView' not found.

Seriously?  This thing happens every time I open up a file from the file icon instead of opening it from a empty scene in maya.

 $exists=0;
 for ($item in `getPanel -scriptType "renderWindowPanel"`) {
        if ( $item == "renderView" ) {
                print "renderView exists.\n";
                $exists=1;
        }
 }
 if ( $exists == 0 ) {
        for ($item in `getPanel -scriptType "renderWindowPanel"`) {
                //print ( $item + "\n");
                if ( $item == "renderWindowPanel1" ) {
                deleteUI renderWindowPanel1;
                $renderPanel = `scriptedPanel -type "renderWindowPanel" -unParent renderView`;
                scriptedPanel -e -label `interToUI $renderPanel` $renderPanel;
                }
        }
 } 

This MEL script will fix it temporarily.
