Adobe embedded in child window causes lock up when focus lost

[Zuldan23]

This is kind of a strange problem but hopefully someone can help. What I am trying to do is embed adobe into a child window but it produces very odd behavior. It loads the PDF just fine but if you have the child window active when you activate any other open window and then go back to it, it is frozen. If you have the parent window active though by clicking the input box and then activate any other window and come back it is fine. This happens if I use "AcroPDF.PDF.1" or "Shell.Explorer.2". Anyone have any thoughts?

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$pdf = ObjCreate("AcroPDF.PDF.1")
$pdf.src = "C:\"
$pdftoload = "" ;add a pdf here to load

$gui = GUICreate("", 600, 800, Default, Default, BitOr($WS_MINIMIZEBOX, $WS_CAPTION, $WS_POPUP, $WS_SYSMENU, $WS_SIZEBOX, $WS_MAXIMIZEBOX, $WS_CLIPCHILDREN))
$btn = GUICtrlCreateButton("Load", 0, 0)
$input = GUICtrlCreateInput("", 70, 0)
    $child = GUICreate("", 500, 700, 50, 50, $WS_CHILD, $WS_EX_CLIENTEDGE, $gui)
    $pdfctrl = GUICtrlCreateObj($pdf, 0, 0, 500, 700)
    GUISetState(@SW_SHOW, $child)

GUISetState(@SW_SHOW, $gui)
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
        Case $msg = $btn
            $pdf.src = $pdftoload
    EndSelect

Will this work for you?

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

$pdf = ObjCreate("AcroPDF.PDF.1")
$pdf.src = "C:\"
$pdftoload = "C:\Sample.pdf" ;add a pdf here to load

$gui = GUICreate("", 600, 800)
$btn = GUICtrlCreateButton("Load", 0, 0)
$input = GUICtrlCreateInput("", 70, 0)
    $child = GUICreate("", 500, 700, 50, 50, $WS_CHILD)
    $pdfctrl = GUICtrlCreateObj($pdf, 50, 50, 500, 700)
    GUISetState(@SW_SHOW, $child)

GUISetState(@SW_SHOW, $gui)
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
        Case $msg = $btn
