I usually select a line of data, for example (B2 through F2) by holding Ctrl and dragging across the row. and then hold Ctrl and click on B4 to deselect it and copy and paste it onto another sheet. It used to work like a dream. Now it is not working. I only use it on a single row. No merged cells. It doesn't work any multiple workbooks I have tried. I even created a new workbook and it did the same thing. Ctrl and click works to select them but not to deselect them. It seems to be selecting the cell twice as the cell gets darker when I select it again and not white like it used to. Any ideas?
