Hi Milos,
if I empty the recycle bin by right clicking its icon in the sidebar it gets emptied. But the former content is still displayed unchanged int the folder content area. If I then select the "This PC" icon just above and change back to the recycle bin, then my drives are displayed still in the folder content area which looks like they are in the recycle bin.
The recycle bin icon in the properties pane still shows the "full bin" instead of the empty one after emptying it, but this is a minor problem.
Regards, Diego
