Two things come to my mind : 1.)When you edit the numbers in those boxes. Don't hit the "enter" key like you would normally do with other programs. 2.)Open Windows explorer. And right click on the .cr2 file for that figure. Select properties. Then see if the Read-only box is checked. If it is. Un-check it and put a check in the "Archive" box. The Read-only option won't let you update them. ScottA
