GUICtrlCreatePic resets window transparency (WinSetTrans)

[therks]

Has anybody else noticed this?

$hGUI = GUICreate('')
WinSetTrans($hGUI, '', 50) ; GUI partially transparent
GUISetState()
Sleep(1000)
GUICtrlCreatePic(@ProgramFilesDir & '\AutoIt3\Examples\GUI\mslogo.jpg', 0, 0) ; Transparency reset to visible (255)

Do
Until GUIGetMsg() = -3
