[OpenLayers-Users] Openlayers displa.. size of the map very small.

Tue Apr 15 16:06:55 EDT 2008

I downloaded a demo which display a nice map through mapserver. The image is like this.
http://www.mobilegeographics.com/mapserver/usa1.phtml

The image is big and nice. 

When I changed it to display throught openlayers. The openlayer map only display a blank windows with all controls. If I change the "proj=lcc" to "proj=latlong" , then it display a map but the size of the map is very small and only occupied the upper lift corner of the openlayers div. Is there any way to make  display fit the windows?

Would like to take any suggestion. Thanks in advance!
