Error 22: Window does not have a constructor

[Ghoulfool-Rz4oxM]

Straight out of the UI textbook we have

   // Create an empty dialog window near the upper left of the screen

   var dlg = new Window("dialog", "Alert Box Builder");

  dlg.frameLocation = [100,100];

  dlg.show();

Half the time this works. The other half the time I get the error 22 Window does not have a constructor. Nice.

Deleting Photoshop preferences doesn't seem to make a difference. The error pops up inconstantly. I can't upgrade from CC 9.1.2 as it's work machine. Running Win 7.

As you can imagine this is just a teeny tiny bit frustrating. Is there a real solution to this? You know apart from defenestration?

Does adding some properties help?

var dlg = new Window("dialog", "Alert Box Builder", undefined, {closeButton: true});
  dlg.frameLocation = [100,100];
 var btn = dlg.add ('button', undefined, "I do nothing")
  dlg.show();

OR This will work with either ScriptUI version. What is Photoshop CC 9.1.2????.  Photoshop version 9 is CS2????  CS6 has an ACR version 9.1.1...

.frameLocation = [x,y] does not work in the new version of ScriptUI.  The Dialog will be centered on your display.

var dlg = new Window("dialog", "Alert Box Builder", undefined, {closeButton: true});  
dlg.frameLocation = [100,100];  
var btn = dlg.add ('button', undefined, "I do nothing")  
runDialog(dlg)
function runDialog(dlg){
   dlg.onShow = function() {
      var ww = dlg.bounds.width;  
      var hh = dlg.bounds.height;  
      dlg.bounds.x  = 100;  
      dlg.bounds.y  = 100;  
      dlg.bounds.width  = ww;  
      dlg.bounds.height  = hh;  
   }
   return dlg.show()
}
