I've tried searching for the answer but I need some help with the connecting the dots.

Using javascript I can open a new browser window by window.open(URL)

Now I have a Ext.Window in my application which in turn contains charts. The client wants the Ext.Window with the charts not to open in the same browser but in a different browser window.

So I'm looking for coding help or tips to how to achieve the following:
window.open(new Ext.Window(...........))

Thanks for all the help!
