I was going to send bug report about tabs popup menu because nothing happen when i clic on it.
Then i turned on my 2nd monitor and see that popup is display on it.
So if we have 2 monitors, Lister is on 1st (left), popup is display on 2nd (right). Borring...
Thanks, I can confirm that (when the window is maximized or the menu button is between the two monitors). We'll fix it.
