Skizo

http://jsfiddle.net/fDcZS/486/I saw this dragging script on the internet but the code has 2 problems.1. If you drag the square and drag it again something strange happens, i cant explain it..2. In google chrome if you're dragging the square the mouse cursor is changing to the text cursor(only when you're dragging).In IE it works fine.Is there a solution?
