I just noticed that although DHE lets me set the icons to a maximum of -15pixels it doesn't use this -15px in the source code when the page is exported.
Martin, I checked your page and all seems to be ok; as you centered the page the program ignores positions that you gave to objects.
IMO you should act as follows: 1- CTRL+A (Select ALL) 2- CTRL+RIGHT ARROW (To move all objects to the right) 3- Enjoy ;-)
When centering the page you can place objects where you want into your D.H.W.E. design, also near the right part of the page; the page will look the same when exported ;-)
