So i adjusted the instructions in Main() in my Startup.class that hides the
FMain window just after showing it.

Public Sub Main()
' snip irrelevant code.

  FMain.Show

  If bStartTray Or If Settings["StartMinimized", False] Then
    If Not bStartOpen Then
    FMain.Hide
    Object.Lock(FMain)
    Wait
    Object.UnLock(FMain)
    Endif
  Endif

End

Locking FMain and using Wait to let the event loop cycle has stopped it
firing the Hide event again.

Without doing that the hide event triggered with the FMain.Hide instruction
and then again after Sub Main() had completed. ??
