*UPDATE*
Working Fiddle... This fiddle produces the error if you follow the instructions
Here's my current problem....
I have a form <div id="blah"></div>
ok so, I use the global block
$.block({ message: $('#blah'),onOverlayClick: $.unblockUI; }); // works
then when the form is submitted, I block the form
$('#blah').block({ message: 'Waiting...' });
on ajax completion
$('#blah').unblock();
this all works, however, once the form is unblocked, I can no longer click the overlay to close the parent form.... from the global block! HELP PLEASE
