Open Adobe Reader window in BSP

Question

Hello,
From our BSP application, I was able to generate PDF form and open a Adobe reader window with the form in it, but after the reader window open, I lose the control for oringal BSP application, the IE windows of BSP application is hanging there, without any response.
Thanks in advance for help!  Here is my implementation:
1) Our BSP application is within CRM IC framework (based on BSP)
2) I created a new BSP page with flow logic with MIME type application/pdf
3) A button trigger page navigation from default.do to new BSP page
4) In OnInitialization event of new BSP page: I code to generate PDF form and open the PDF window:
  call method response->set_content_type
    EXPORTING
      content_type = 'application/pdf'.
  response->set_header_field(
                    name  = 'content-disposition'
                    value = 'attachment; filename=Act_Printing.pdf' ).
finally display PDF format in Browser
  l_pdf_len = xstrlen( l_xstring ).
  response->set_data( data   = output-pdf
                               length = l_pdf_len ).
***Up to now: a new adobe reader window is opened , but the oringal BSP window lose the control.
If I add extra code to navigate to default.do as below, I did get control of the BSP window BUT the adobe reader window does not open at all:
Navigate to default.do
  navigation->next_page( 'BACK_TO_CONTROL' ).
navigation->next_page( 'BACK_TO_CONTROL' ).

Thanks Durairaj  !
I tried navigation->response_complete( ), but it does not change the system behaviour, the same problem is still there.
Any idea?
