I have tried to make a script that copies every spread of every document of a choosen directory to a new document. This script works, but after saving and closing the target doc and throwing out the message "Ready" InDesign CS2 (4.0.4, OSX 10.4.7) crashes - every time!

Does anybody have an idea why InDesign crashes?
Is there a better way to do the job?



 
var myDoc = app.documents[0]; 
var myFolder = Folder.selectDialog("Choose directory");	 
if(myFolder != null){  
	var myFiles=myFolder.getFiles("*.indd");  
	if (myFiles.length>0){  
		var myCollectedFileName="_"+ myFolder.name + ".indd";  
		var myFirstDoc = app.open(myFiles[0]); 
		var myTargetDoc = app.documents.add(); 
		myTargetDoc.pages.add() 
		myTargetDoc.documentPreferences.properties = myFirstDoc.documentPreferences.properties; 
		myFirstDoc.close(SaveOptions.no); 
		for (k = 0; k < myFiles.length; k++) { 
			collectDocFiles(myFiles[k]);  
		}

		var myColFile = new File(myFolder + "/" + myCollectedFileName);	  
		myTargetDoc.save(myColFile); 
		myTargetDoc.close(SaveOptions.no); 
		alert("Ready") 
	}  
}

function collectDocFiles(theDocFile) {  
	var mySourceDoc = app.open(theDocFile);  
	if ((myTargetDoc.documentPreferences.facingPages == true) && (myTargetDoc.spreads[-1].pages.length != mySourceDoc.spreads[0].pages.length)) 
		myTargetDoc.pages.add(); 
	for (oneSpread = 0; oneSpread < mySourceDoc.spreads.length; oneSpread++)  
		mySourceDoc.spreads[oneSpread].duplicate(LocationOptions.after,  myTargetDoc.spreads[-1])  
	mySourceDoc.close(SaveOptions.no);  
}
