Capture NX version 1.3 damages the raw file when writing the adjustments. The error is not critical, except for some applications, which reject such files or process them incorrectly (iPhoto, PhotoMatix, ...).
Nikon Capture X and Adobe Camera Raw have no problem with these files.
Capture NX version 2 adds another error, even less important.
For a more detailed description of the errors and correction (Windows only) look for "Spin-off programs"
