Hi Rob,
I’m pretty sure the is a bug in the return parameter. Entering something like http://www.lovesafecracker.com/tg/t gets mangled to http://www.lovesafecracker.com/http://www.lovesafecracker.com/tg/t when the form is submitted. An extra http://www.lovesafecracker.com/ gets tacked on the front.
Cheers
Lee
