BT126H_Mail To Field Getting reset.

Hi,

in the BT126H_Mail the Email-To address is filled through variable gt_to,  its getting reset from memory after user changes the defaulted email address.

it happens after Do_request is triggered by the system..   I even redefined the controller class (Do_REQUEST method)

My requirement is if the user changes the defaulted email address in the To Field it should not change again.

Thanks
