OS Win 7
left click and ctrl+left click act the same.
example: L-click on 3 files, one after another and all 3 stay selected, L-click on a selected file and it is unselected and the others stay selected.
very confusing and does not allow drag-drop of a selection of files because after making the selection L-click and hold just unselects the file clicked on.
also cannot ctrl+L-click to drag a copy.
How do I turn this off?
