I changed that loop to:
        windowSize[0] = temp[2];
        windowSize[1] = temp[0];
        windowSize[2] = temp[3];
        windowSize[3] = temp[1];

but I still get the "Selection must have a single node" error. Can you
send your working code (or preferably edit the wiki page directly :)
).
