Just find a new picture that xnview don't have thumbnail cache.
ctrl+x in windows explorer. (don't use ctrl+x in xnview! or it will not be reproduced)
paste file in xnview. Now this file have wrong date.
(I'm using xnview MP 0.83)
Seems small file can't reproduce this bug!
I'm using a png file with the size bigger than 4MB.
The date on attachment is create , modify , access time.
