So  what does "longitude -32.8, or 32.8W" mean? and why computer tell me"the longitude difference is more than +-15 degree"? <BR>  <BR> thank you for your answer.<BR>  <BR> kind regards,<BR> Paul<BR><br /><hr />MSN保护盾，十八般武艺保障MSN安全！ <a href='http://im.live.cn/safe/' target='_new'>现在就下载！</a></body> </html>
