Topic: How to delete extra space around tiltviewer

Hi I have installed TiltViewer in my site … index.html.  The problem I have is that there is a lot of blank space above the tiltviewer and although on my big screen it looks great .. on my laptop you can just see the top edge of it, and unless you knew it was there .. you wouldnt see it .. and there are no scroll bars.  I have tried alterting the height % in the css  .. but this makes no difference to the display on my laptop.  Appreciate any feedback from others who may have encountered the same problem.  Thanks
