Using ColorBox to popup "iFrame" shows original page content after the "iFrame" data?
OK, so originally I had tried echo $data; then return;

I then tried: return $data; but that kept showing the header/footer.

I've found that this works well:

echo $data;
die;


Though it's probably not the best way to do it, but it works for the way the module was wrote... should really use the Node/Entity API next time :)
