title: if unchecked script still working :( with ui.boxer whats wrong?
body: <p>Hello I have a problem with this <a href="http://jsfiddle.net/E7dGA/1/" rel="nofollow">http://jsfiddle.net/E7dGA/1/</a>
  When the script starts and you don't check the checkbox everything is ok - the drawing doesn't occur. Next, when you check the box, still everything is ok (you can draw divs), but when you uncheck the checkbox, the you can still draw divs even if the checkbox is unchecked???</p>
  
  <p>Whats wrong?</p>
