Script Summary: A little window fixed to a certain position on the screen, drag and drop supported.
A simple drag&drop window to be included on a page, for testing purposes only.
Special thanks to quirksmode.com, where most of the code was taken from:
http://www.quirksmode.org/js/dragdrop.html
(The keyboard control had to be commented out due to some tricky event handling that is not compatible with Greasemonkey. Perhaps it will come in another release - or someone else will work it out.)
