Change image back after hover

[AcidCorps]

This script is pretty long at this point (a lot of directory reading and web reading) so I'm only going to include the part that I need help on

While 1
    $Msg = GUIGetMsg()
    $Hover = _ControlHover(0)
    If $Hover = 1 Then
        Prewview(@Extended)
    EndIf
    If $Hover = 0 Then GuiCtrlSetImage($GuiBackground, $GuiWallpaper)
    Select
        Case $Msg = $Exit
            Exit
    EndSelect
WEnd

Func Prewview($xControl)
    $Text = GuiCtrlRead($xControl)
    For $i = 1 to $GuiMenuItems[0][0]
        If $Text = $GuiMenuItems[$i][0] Then
            $Element = $i
            ExitLoop
        EndIf
    Next
    $PreviewPic = @ScriptDir & '\' & IniRead($GuiMenuDir & $GuiMenuItems[$Element][1], 'Data', 'ImagePreview', 'bin\menuitems\images\movies.jpg')
    GuiCtrlSetImage($GuiBackground, $PreviewPic)
EndFunc EndFunc

my problem is I can get the iamge to change when the button is hovered over but when I try to add

If $Hover <> 1 Then GuiCtrlSetImage($GuiBackground, $GuiWallpaper)

it flickers the image I want to have when its hovered and then just flickers the background image a lot

Thanks in advance

Maybe you should try to set the image once instead of 100 times a second?

$globalflag = 0
While 1
    $Msg = GUIGetMsg()
    $Hover = _ControlHover(0)
    If $globalflag = 0 And $Hover = 1 Then
        $globalflag = 1
        Prewview(@Extended)
    EndIf
    If $globalflag = 1 And $Hover = 0 Then
        $globalflag = 0
        GuiCtrlSetImage($GuiBackground, $GuiWallpaper)
    EndIf
    Select
        Case $Msg = $Exit
            Exit
    EndSelect
WEnd

Edit:Wait... That's not right. Better now?
