To your answer... yes the arrows are located in the middle of the browserwindow and thats fine. But the magazin itself sticks on the top of the browserpage. I have some A4 landscape magazins and the are located on top... i want to have the magazin vertical->centered that there is a little space on the top of the page and the same space to the bottom. Then the arrows are automatically are in the middle of the magazin...
