How to stop "Please select the view you want to render" dialog box in Maya

If a camera view loses focus and you try to render, Maya will ask you "Please select the view you want to render." This gets really annoying.  To make Maya assume you want to render the last view that was selected, make the following changes.  These instructions are for Maya 6.0.1.

1. Copy the file 'renderwindowpanel.mel'
   
   C:\Program Files\Alias\Maya6.0.1\scripts\others\
   
   to
   
   C:\Documents and Settings\<USERNAME>\My Documents\maya\scripts
2. In the copied 'renderwindowpanel.mel', locate proc 'renderIntoNewWindow'
3. Replace this text...
   
   

   if ($camera == "") {
         confirmDialog
                -message "Please select the view you want to render" 
                -button "OK"
                -defaultButton "OK";
         return;
   }
   
   with...
   
   if ($camera == "") {
         string $editor = `getRenderWindowPanel`;
         $camera=`renderWindowEditor -q -currentCamera $editor`;
         if ($camera == "") {
               // never rendered any panel
               confirmDialog
                      -message "Please select the view you want to render"
                      -button "OK"
                      -defaultButton "OK";
               return;
         }
   }
