VB6 Test case (source code) AND exe

Many of my utilities run minimized and are supposed to popup when they are
ready for interaction.

To make them popup I use this code:

Me.WindowState = 0
  BringWindowOnTop Me.Hwnd
  FlashWindow Me.Hwnd, True
  Me.Caption = "Popped up"

Public Sub BringWindowOnTop(Hwnd As Long)
    SetWindowPos Hwnd, HWND_TOP, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
    SetWindowPos Hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
    SetWindowPos Hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
End Sub

The above code works on XP and W7.

On Wine as soon as I call HWND_NOTOPMOST the window falls behind other windows,
unless I give the window focus before that happens. (that is not part of the
submitted test case)
