This update of the script adds a modification that will stretch the actual map to the height of your browser area.

If you don't like this, you can modify the script yourself to your liking. The line that changes height is:

addGlobalStyle('#page { position: relative; width: 100%; height: '+window.innerHeight+'px; z-index: 0; }');

It is found at the end of the do_platypus_script function.
