</STYLE>
<SCRIPT>
window.onload=fnInit;
var iOffset=10;
function fnInit(){
oDiv.setAttribute("moving",false);
oDiv.style.left=document.body.clientWidth/2 - oDiv.offsetWidth/2;
oDiv.style.top=oOffset.offsetTop  + oOffset.offsetHeight + iOffset + oBlock4.offsetHeight + 10; oBlock1.style.setExpression("top","oDiv.offsetTop - iOffset - oBlock1.offsetHeight");
oBlock1.style.setExpression("left","oDiv.offsetLeft + (oDiv.offsetWidth/2 - oBlock1.offsetWidth/2)");
oBlock2.style.setExpression("top","oDiv.offsetTop + oDiv.offsetHeight +  iOffset");
oBlock2.style.setExpression("left","oDiv.offsetLeft + (oDiv.offsetWidth/2 - oBlock2.offsetWidth/2)");
oBlock3.style.setExpression("top","oDiv.offsetTop + (oDiv.offsetHeight/2 - oBlock3.offsetHeight/2)");
oBlock3.style.setExpression("left","oDiv.offsetLeft - iOffset - oBlock3.offsetWidth");
oBlock4.style.setExpression("top","oDiv.offsetTop + (oDiv.offsetHeight/2 - oBlock4.offsetHeight/2)");
oBlock4.style.setExpression("left","oDiv.offsetLeft + oDiv.offsetWidth + iOffset");}
function fnStartMove(){
oDiv.adjustX=event.clientX - oDiv.offsetLeft;
oDiv.adjustY=event.clientY - oDiv.offsetTop;
oDiv.moving=true;
}
function fnStopMove(){
oDiv.moving=false;
}
function fnMove(){
if(oDiv.moving==true){
if(event.clientX - oDiv.adjustX>0){
oDiv.style.left=event.clientX - oDiv.adjustX;
} if(event.clientY - oDiv.adjustY>0){
oDiv.style.top=event.clientY - oDiv.adjustY;
}
}
}
function fnUpdate(){
iOffset=parseInt(oOffset.value);
}
</SCRIPT>
<P><input TYPE=text VALUE="10" onkeyup="fnUpdate()" ID="oOffset"></P><DIV ID="oDiv" CLASS="block" STYLE="cursor: move;" onmouseout="fnStopMove()" onmouseup="fnStopMove()" onmousemove="fnMove()" onmousedown="fnStartMove()"></DIV>
<DIV ID="oBlock1" CLASS="block2"></DIV>
<DIV ID="oBlock2" CLASS="block2"></DIV>
<DIV ID="oBlock3" CLASS="block2"></DIV>
