It seems that xnview doesn't recognize 16-bit images. Sorry it does recognize them, I can open and view such image, but in properties page the "bits per pixel" says that there're 32 bits when there are 16*4=64 bits. This is not a big problem since I can do with this image anything I want, but it seems like something unfinished, you know...
And 1.9 alpha 3 behaves alike.
I can send you example files.

XnView can load it, but it displays wrong information about it in the status bar. After converting to another format (e.g. JPEG2000) the image really contains only 8bpp, so the high precision is lost.
XnView doesn't support more than 8bits per component, and all 10/12/16/24/32bits will be converted in 8
