[Gimp-user] GIMP 2.10 TIFF EXIF metadata stripped on Windows 10

[MartinFa <forums gimpusers com>]

This is getting stranger...

I'm away from home right now, since last night, & using GIMP 2.10 on my laptop -
Win 10, once again. I can't reproduce the problem on this machine. I thought it
might be to do with the fact that the original tiff files I was playing with on
my desktop at home were Black & White, but I just tried with B/W (and colour)
tiffs from the same photo scanner here on my laptop: all seems ok.

I'll have another look on my desktop machine when I get home next week.
