XnView Software

thanks pierre, had the same issue. your answer was helpful!

yes, you are correct - but is it normal that a tab with the same picture as in the fist tab opens so that you have two tabs with the same picture?

From my point of view, if a tab with picture1 is already opened you don't need to open it a second time.

Regards

Confirmed

and in addition (to clarify the above):

not a second file is produced but a second tab with the first file opens!
