In this line:

   oDiv.onmouseout=function(e) {OnMouseOut(e,tcAlignID,lnLeft,lnTop,lnWidth,lnHeight)}
   lnLeft=lnLeft-tnAlignOffsetLeft
   lnTop=lnTop-tnAlignOffsetTop

The values of lnLeft and lnTop, for example, are passed by reference.

However, once the event is triggered, the value is not what was passed but the adjusted value in the lines following.

What would be the best approach to pass a variable value?
