Windows positioning after upgrade

I have a menu item I use to open a window on my page. I am upgrading to the new release of dhtmlx and am now having problems with dhtmlx windows y-coordinates not working. I can’t move it below my menu… I can move it up though. The x-coordinates work fine, but it seems to ignore y.

I sure could use some help. This is the code:

The default viewport is document body. So, check that body has desired width and height:

html,body{ width:100%; height:100%; }

That did it thank you. I neglected to set the html descriptor.
