When I press the "Rescan now" Button nothing happens. And the new items are not added to the volume. Respecteively they are not shown.
Now it suddenly is scaned, I do not know why. Two or more different Everything windows were open. At least some of them does not show the new items of the USB stick. So maybe it was scaned immediately, but one or more of the windows were not updated?
So one has to close the other windows and re-open them to get them udpated?
