XnView: MP 0.99.7 - 64 bit
OS: Windows 10 21H2 / 64bit
Effect: <If a NEF-file is selected ITPC-IIM data is not shown in the info field (even creator information from the camera is not shown, if ITPC data is changed via Ctrl-I the data is not written to the file>
To reproduce:
1. Select a NEF file
2. Press Ctrl-I
3. Change a field
4. Write to file
Actual behaviour (bug): After the write the EXIF tab in the info field is selected but empty The IPTC tab is added and contains the information entern, but if the image is de-selected and then re-selected the IPTC tab is not displayed anymore. CTRL-I reveals that the entered IPTC information is not in the file or not retrieved. For NEF files, which contain IPTC information the information is not shown.

Expected behaviour: IPTC data should be written to the image file and displayed as contained in the image file as it worked before v0.99.6.
The fix provided does not work anymore. Can't find the paramter RAWUSElibraw in xnview.ini anymore.
