The mouse in SU 2015 must be clicked twice to select something. Example: Open a new blank page and click one time on the image of the man standing. Nothing happens. Click again and he is selected. Then click onece in an empty area and nothing happens. Click again and the man is de-selected.
Second example: Open a new page in SU 2015. Click once on the man. Nothing happens. Move the mouse to an empty space and click again, The man is selected!
Is there something that can be changed to fix this?
