external form

Internet Explorer 11 form inputs problem

When using an external form for a process the input texts seems to be disabled or blocked I cant write anything on them this problem only happen with internet explorer, this behavior happen the second time I load the form the first time works fine.

Full External page visualization.

when I use the External url option for a task form, Bonita display it inside it´s portal view through an iframe I guess, is there a way to avoid using that iframe and display the full form in browser?
