_GDIPlus and Buttons gone after minimize restore

[shotiko]

i have a code that creates buttons and graphics in the same block.  before the block is _GDIPlus_Startup()

$hGraphic = _GDIPlus_GraphicsCreateFromHWND($mainGUI)

        $hBrush = _GDIPlus_BrushCreateSolid(0xF03FC744) ; Felish Green colour
        $hPen = _GDIPlus_PenCreate(0xFFBFCC49); Granite colour
        $hPath = _GDIPlus_PathCreate() ;Create new path object
        $hFamily = _GDIPlus_FontFamilyCreate("Tahoma") ;Create font family object

        $tLayout = _GDIPlus_RectFCreate($startX, $startY, $bHeigh, $bWidth) ;Create string bounding rectangle X=0, Y=0
        $hFormat = _GDIPlus_StringFormatCreate(0x0400); Allow overhanging rectangle
        _GDIPlus_StringFormatSetAlign($hFormat, 1); Align text horizontally
        _GDIPlus_StringFormatSetLineAlign($hFormat, 1) ; Align text Vertically

        ; Add String like CtrlLabels assign to rectangle and formats including Font _
        _GDIPlus_PathAddString($hPath, FileReadLine($configF, $SN), $tLayout, $hFamily, 0, 26, $hFormat)

        _GDIPlus_GraphicsSetSmoothingMode($hGraphic, $GDIP_SMOOTHINGMODE_HIGHQUALITY) ;Sets the graphics object rendering quality (antialiasing)
        _GDIPlus_GraphicsFillPath($hGraphic, $hPath, $hBrush) ; Fill path to graphics handle (GUI)

end of the block

_GDIPlus_BrushDispose($hBrush)
    _GDIPlus_FontFamilyDispose($hFamily)
    _GDIPlus_StringFormatDispose($hFormat)
    _GDIPlus_PenDispose($hPen)
    _GDIPlus_GraphicsDispose($hGraphic)
    _GDIPlus_Shutdown()

now this works on the first run but when i minimize and then restore _GDIPlus_ is gone and so are buttons. but if i create labels they stay.

i've tried moving "Dispose" functions at the end of the loop but still the same result

You have to redraw the GDI+ stuff when restoring the GUI.
