Open up "Save As" dialog in javascript

Question

Hello all,
     I am a newbie to scripting and to be honest it makes my head hurt lol, Kudos to all that make this look easy. I found some good resources but following everything is going to take a bit. I have am using the object model viewer and its a great resource. Long story even longer I am trying to automate a bunch of repetitive tasks that we have to run on a ton of pre-built documents. I have been hobbling together some code that has been working. everything is working and I can worry about cleaning up the code later (for my sake. I have OCD)
I can't seem to find a way to open up the "save as" dialog so that the user can save the document to a directory that will change from week to week. The file name will vary across the run of files. I don't need anything to automate that part. I just want it to pop up and then continue the run. I'd like to do this at the start of the script so that when all the changes are made I can just have the document close. (I haven't included the closing code yet) Is this possible? I cant seem to find anything out there to point me in the right direction.
Here is what I have so far.
myDoc=app.activeDocument; 
for (var  n=myDoc.masterSpreads.length-1; n>=0; n--){ 
     if (isMasterSpreadInUse(myDoc.masterSpreads[n])==false){ 
          myDoc.masterSpreads[n].remove(); 
function isMasterSpreadInUse(myMasterSpread){ 
     var myDoc=myMasterSpread.parent; 
     for (var  n=myDoc.masterSpreads.length-1; n>=0; n--){ 
          if (myDoc.masterSpreads[n].appliedMaster==myMasterSpread){ 
               return true; 
     for (var  n=myDoc.pages.length-1; n>=0; n--){ 
          if (myDoc.pages[n].appliedMaster==myMasterSpread){ 
               return true; 
     return false; 
Array.prototype.filter = function(collection) { 
          var k, i, con, ids = collection.everyItem().id; 
          con: for (k = ids.length - 1; k >=0; k--)  
                    for (i = 0; i < this.length; i++) 
                    if (this[i].id == ids[k]) { 
                         ids.splice(k, 1);  
                         continue con; 
          return ids;     // array with unmatched ids from collection 
var  
          mL = app.activeDocument.pageItems.everyItem().itemLayer, 
          mUnusedLayersID = mL.filter(app.activeDocument.layers), 
          len = mUnusedLayersID.length; 
while (len-->0) 
          app.activeDocument.layers.itemByID(mUnusedLayersID[len]).remove();
var layers = app.activeDocument.layers.everyItem().getElements();
for(var i=layers.length-1;i>=0;i--){
if (layers[i].name[0] == "X"){
     layers[i].remove();
app.documents.everyItem().xmlElements.item(0).xmlElements.everyItem().untag();
myPreset = app.printerPresets.item("AdQ 8½x11");
app.activeDocument.print(false, myPreset);

I've suddenly started getting this issue today on SSMS 2008 with Win 7.  I can do Save but as soon as I try Save As the whole thing just locks up.  I get a flashing Save icon in the bottom right corner but no Save dialog and all I can do at
that point is close the whole thing down using Task Manager.
Does anyone know if there is a fix for this?
