Why doesn't a particular label (GUI) show?

[Chicken Scartch]

The code below was taken from a script I recently wrote. What I want to know is why $lblDisplay doesn't show up once the GUI/Canvas gets painted onto the screen? I first thought it was because $lblDisplay is actually empty since it is not displaying anything, but then - $lblBackground shows up and it is also "empty". To solve this, I actually had to move the $lblDisplay below "GUISetState(@SW_SHOW)". I'm just curious why this is happening.

Thanks for your insights.

#include <GUIConstants.au3>

; Create the canvas
$frmMain = GUICreate("ICP Workstation GUI", 616, 434, 327, 174)
; Set the icon to be used at the top left corner of the window
    GUISetIcon("C:\Documents and Settings\Koua Lo\My Documents\icons\Mac Hardware\iMac.ico")
; Create the "System Information" group
        $grpDisplay = GUICtrlCreateGroup(" System Information ", 240, 8, 368, 417)
        $lblDisplay = GUICtrlCreateLabel("", 254, 56, 340, 356, $WS_VSCROLL)
        $txtLookup = GUICtrlCreateInput("", 246, 24, 281, 21)
        $btnSearch = GUICtrlCreateButton("Search", 530, 24, 70, 21, 0)
        $lblBackground = GUICtrlCreateLabel("", 247, 48, 353, 372, -1, $WS_EX_STATICEDGE)
        GUICtrlCreateGroup("", -99, -99, 1, 1)
; Individual buttons
    $btnMySys = GUICtrlCreateButton("My System Info", 8, 13, 89, 21, 0)
    $btnPing = GUICtrlCreateButton("Test Network", 8, 36, 89, 21, 0)
    $lstMain = GUICtrlCreateList("", 104, 13, 129, 409); List viewer
    $btnExit = GUICtrlCreateButton("E&xit", 8, 400, 89, 21, 0)
    $btnClear = GUICtrlCreateButton("&Clear", 8, 59, 89, 21, 0)

; Paint the canvas onto the screen
GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $btnExit
            Exit
    EndSwitch
WEnd

Maybe I'm missing something but it appears that since you have your background 'drawing' after the lbldisplay its 'drawing' over it.

#include <GUIConstants.au3>

; Create the canvas
$frmMain = GUICreate("ICP Workstation GUI", 616, 434, 327, 174)
; Set the icon to be used at the top left corner of the window
    GUISetIcon("C:\Documents and Settings\Koua Lo\My Documents\icons\Mac Hardware\iMac.ico")
; Create the "System Information" group
    $lblBackground = GUICtrlCreateLabel("", 247, 48, 353, 372, -1, $WS_EX_STATICEDGE)
        $grpDisplay = GUICtrlCreateGroup(" System Information ", 240, 8, 368, 417)
        $lblDisplay = GUICtrlCreateLabel("54654654654654", 254, 56, 340, 356, $WS_VSCROLL)
        $txtLookup = GUICtrlCreateInput("", 246, 24, 281, 21)
        $btnSearch = GUICtrlCreateButton("Search", 530, 24, 70, 21, 0)
        ;$lblBackground = GUICtrlCreateLabel("", 247, 48, 353, 372, -1, $WS_EX_STATICEDGE)
        GUICtrlCreateGroup("", -99, -99, 1, 1)
; Individual buttons
    $btnMySys = GUICtrlCreateButton("My System Info", 8, 13, 89, 21, 0)
    $btnPing = GUICtrlCreateButton("Test Network", 8, 36, 89, 21, 0)
    $lstMain = GUICtrlCreateList("", 104, 13, 129, 409); List viewer
    $btnExit = GUICtrlCreateButton("E&xit", 8, 400, 89, 21, 0)
    $btnClear = GUICtrlCreateButton("&Clear", 8, 59, 89, 21, 0)

; Paint the canvas onto the screen
GUISetState(@SW_SHOW)

While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $btnExit
            Exit
    EndSwitch
WEnd

EDIT: I should probably be a bit more descriptive... sorry hunger talking. I moved the $lblBackgroung to the top, allowing the lbldisplay to draw over it. I commented out the original line so you could see what I did.
