Programmatic copy vs. manual copy

What is the hidden secret here?

1. The script is copied from a desktop-subdirectory into FrameMaker Startup by mans of an installation program.
2. The script is manually copied (using File explorer) from the desktop-subdirectory into FrameMaker Startup.

Starting FM after case 1 executes the script twice !

Starting FM after case 2 executes (as expected) the script once.

I have cut down my script to something manageable and did the tests with this stub.

// FMdict_test.jsx ------ UTF-8 ------------------------------------------------------------------------
#target framemaker
ShowDictInfo ()                                   // At start of FM inform about the User dictionary
SetUpMenus()    // inactivate for debugging       // Establish menu item to get the information also later.
function SetUpMenus() { // =========================================================================
// This function MUST NOT be named DefineMenu - because this is a reserved function!
  var sDictMenu  = "Dictionary information";
  var sShortLbl  = "ESC q d i";
  var sShortCut  = "\\!qdi";
  var menuLocation = app.GetNamedMenu("FileMenu"); 
  var cmdDoc       = menuLocation.DefineAndAddCommand(1, "FMdict_DocInfo", sDictMenu, sShortCut);
  cmdDoc.KeyboardShortcutLabel = localize(sShortLbl);  
  UpdateMenus();                                  // refresh and actually make the new menu appear
  
} // ---  end SetUpMenus
function Command(cmd){
  switch(cmd) {
    case 1:
     ShowDictInfo();
     break;
  }
} // --- end Command
function ShowDictInfo () { // === Alert the dictionary information ================================
var appdata    = app.UserSettingsDir;             // %appdata%\Adobe\FrameMaker\<version>
var FMdictDir  = appdata.replace (/Adobe.*/ , "D+DD\\FMdict");
var iniFile    = FMdictDir + "\\scripts\\FMdict.ini";
var title      = "FMdict — Dictionary information";
var currentPrj = "current Project"                // GetIniValue (iniFile, "currentPrj");
var currentDir = "current Directory"              // GetIniValue (iniFile, "currentDir");
var text       = "The User dictionary was loaded from \nFMdict project:\t" + currentPrj + "\nLocated in:  \t" + currentDir;
  if (currentPrj !== "NONE") {                    // must fit with FMdict
    alert (text, title, false);
  }
}

the installation routine is a compiled AHK (AutoHotKey) script which uses this statement:

  FileCopy, %installDir%\scripts\*.jsxbin, %FMtarget%, 1

This expands to

  FileCopy, C:\Users\Klaus\Desktop\InstallThis\scripts\*.jsxbin, C:\Users\Klaus\AppData\Roaming\Adobe\FrameMaker\14\Startup, 1

Parameter 1 allows to overwrite an existing file.

After deleting the target file I repeated the experiment with the command prompt:

Copy C:\Users\Klaus>copy C:\Users\Klaus\Desktop\InstallThis\scripts\*.jsxbin C:\Users\Klaus\AppData\Roaming\Adobe\FrameMaker\14\Startup

This copied script also hits twice!

Find the jsxbin here - it shoud be the same if you 'Export as Binary' the above script.

A very bewitched situation...
