Hi Tim,

Thanks for your answer. I have checked the file with SeaClear 
(<http://www.sping.com/seaclear/>), and the coordinates are correctly 
displayed.

On this screen shot <http://dl.free.fr/qu2tpayGr>, I have put the cursor 
on the map at 20°N, 120°W, and you can see that the coordinates 
displayed at the lower right corner of the screen are correct.

Best regards,
Jean-Claude
