"For old people, it is difficult to click button on mouse but do not move it." It took me a while to notice this when my mom uses her computer. I had been supporting her remotely using VNC, and couldn't figure out why her windows were resized to be small. When I visited her in person, I saw that she was trying to close a window, but when she click the mouse button, she also move the mouse over to a border, held the mouse down, and ended up reszing the window. Solution: - configure larger window decorations (scroll bars, close buttons.) - configure larger window borders.
