// Notes: 
// 1. If the page already has an window.onload then we must include SetPos in that function on the page itself	
// 2. If the body of the page is too wide then you will see bottom scroll bars. In that case (e.g. ccm.htm) just 
//    set body width <div id="body" style="visibility: hidden;  width:620">
// SetPos is now called via onload of first image in Right border
// but the include of getScreen.js is in body page
// 110802 Occasional blank screens. Include window.onload as belt and braces
// 110821 No, problem with multiple onload's - remove again
//window.onload=SetPos

//alert("Here")

//alert("pageWidth: " + pageWidth())

// The 20 deduction is to allow for RH scrollbars
// IE includes them in width, Firefox seems to account for them i.e. has net screen width
// Result is that FF right border is further 20 to left
Pad = ((scnwidth - 20 - 920) / 2)
