No file-deselection after drag-and-drop

[DaDoc]

When I check "Unselect files and folders when Copy Operation start" in "Explorer Panel settings", mark some files and press "F5" to copy these files, all selected files are deselected after copying and thats ok. But when I'm using drag-n-drop between the panels to copy the selected files, the selection will stay so I've to deselect the files manually (or do a "Refresh").
