Murali, <br>
<br>
Do you have some sample code that you could paste? It's hard to debug these sort of things without a good stack trace. <br>
<br>
One thing that comes to mind is are you setting the width and height
properties on your map div? the getCurrentSize() function below first
tries to read clientHeight/Width but if that fails, it uses the
getDimensions() function and then as last resort style.height and
style.width. <br>

/**<br>
* @private <br>
* <br>
* @returns A new OpenLayers.Size object with the dimensions of the map div<br>
* @type OpenLayers.Size<br>
*/<br>
getCurrentSize: function() {<br>
<br>
var size = new OpenLayers.Size(this.div.clientWidth, <br>
this.div.clientHeight);<br>
<br>
// Workaround for the fact that hidden elements return 0 for size.<br>
if (size.w == 0 && size.h == 0 || isNaN(size.w) && isNaN(size.h)) {<br>
var dim = OpenLayers.Element.getDimensions(this.div);<br>
size.w = dim.width;<br>
size.h = dim.height;<br>
}<br>
if (size.w == 0 && size.h == 0 || isNaN(size.w) && isNaN(size.h)) {<br>
size.w = parseInt(this.div.style.width);<br>
size.h = parseInt(this.div.style.height);<br>
}<br>
return size;<br>
