>All is ok when I do it. I clicked on the last two days icon. Then, from the treeview, I opened several categories. Then, from related threads, I opened a few of them. All is ok for me. Can you be more precised about what I should look for, where to click exactly, on which category, on which thread, etc.?

Ok.
1) Click on 2 days view icon.
2) Each message, which says, for example, [8/8] is repeated 8 times. If it says, [2/2] it repeated twice. Also the originator of the thread is shown. I was quite surprised to see my old thread, BTW :)
