Pb with b&w TIFF

[lorseau]

i use xnview for a while and it's the first time i have this problem:
when i display black & white TIFF, the thumbnail (and also the normal size) image on xnview i just see some noises...
and the problem appears just with b&w tiff, there is no pb with colour tiff...

is it a problem from xnview or a problem on my computer?
does someone know a solution for this problem?

thanks,
laurent
