[Typo3] OT: JavaScript depends on Doctype?

Sat Sep 24 22:53:01 CEST 2005

Hi Heiner. It's because you need to prefix the positions with a unittype, 
like "px".

Change:
  document.getElementById("marker").style.marginLeft = xPos - 5;
  document.getElementById("marker").style.marginTop = yPos - 5;

Into:
  document.getElementById("marker").style.marginLeft = (xPos - 5)+"px";
  document.getElementById("marker").style.marginTop = (yPos - 5)+"px";
