• When terminal window shrinks horizontally, the box and message are not showed.
• When terminal window is enlarged horizontally, the box and message are showed but right vertical line is missing
• When terminal window shrinks vertically, the box and message are showed but horizontal bottom line is missing
• When terminal window is enlarged vertically, all run as expected.

Is there another way to refresh the screen?
