fade out and background

[Laetterman]

how do i fade out a window with a pic with a transparent backgroundcolor? following exemple fades out a 'close'-button in two different ways. At the beginning the image is cut out correctly and the background is transparent. But while fading out there is always blue background... why?!

#include <GUIConstants.au3>
#include <Array.au3>
HotKeySet("{ESC}", "f_Terminate")

AutoItSetOption ( "TrayIconDebug", 1 )
Opt("WinTitleMatchMode", 3) 
Opt("GUIOnEventMode", 1)

$parent = GUICreate("Gui", 200, 100, 50, 45, BitOr($WS_POPUP, $WS_BORDER), BitOr($WS_EX_TOPMOST,$WS_EX_TOOLWINDOW))
$close = GUICreate("Close", 17, 20, @DesktopWidth/2, @DesktopHeight/2, $WS_POPUP, $WS_EX_LAYERED, $parent)
GUICtrlCreatePic(@ScriptDir & '\close2.gif', 0, 0, 17, 20)
GUISetState (@SW_SHOW)

Sleep(3000)

For $i = 0 To 255
        Sleep(10)
        WinSetTrans($close, "", 255-$i)
    Next

Sleep(3000)
WinSetTrans($close, "", 255)
GUISetState (@SW_SHOW)

DllCall("user32.dll", "int", "AnimateWindow", "hwnd", $close, "int", 3000, "long", 0x00090000);fade-out


Func f_Terminate()
        Exit
    EndFunc
