Like in Delphi, TApplication always shows the "main form" (the first
form registered with App.AddForm) when Application.Run is called.
You must toggle Application.ShowMainForm
(http://lazarus-ccr.sourceforge.net/docs/lcl/forms/tapplication.showmainform.html).
I guess it's preferable to call it just after Application.Initialize
(in the .lpr), but maybe just calling it before Application.Run is
enough.
