Hello,
up to now I have used the DHTMLX 3.6 
version with which I have always found myself very well. Today I decided to try version 6 and I immediately found some problems. The first is what I can’t attach a page to a window.
Example: I have the page form.php that is a form that I want to use in different pages. Now on the pages I want to open the form on a window. On my version the code was something like:
dhxWins = new dhtmlXWindows();
dhxWins.enableAutoViewport(true);
dhxWins.setImagePath(“dhtmlx/dhtmlxWindows/codebase/imgs/”);
w1 = dhxWins.createWindow(“w1”, 20, 30, 440, 704);
w1.attachURL(“form.php”);
dhxWins.window(“w1”).center();
