            -----------------------------------
            1.1) Click on the Choice.
            1.2) Press and hold down the left button of the mouse to select (eg) item 5 in the choice.
            1.3) Drag the mouse vertically out of the area of the open list,
                 keeping the X coordinate of the mouse position about the same.
            1.4) Check that when the Y coordinate of the mouse position is higher than the upper bound of the list
                 then the list continues to scrolls UP and the selected item changes at the top until you reach the topmost item.
                 If not, the test failed. Press FAIL.
            1.5) Check that when the Y coordinate of the mouse position is lower than the lower bound of the list
                 then the list continues to scroll DOWN and the selected item changes at the bottom until you reach the bottommost item.
                 If not, the test failed. Press FAIL.
            -----------------------------------
            2.1) Click on the Single List.
            2.2) Press and hold down the left button of the mouse to select (eg) item 5 in the list.
            2.3) Drag the mouse vertically out of the area of the open list,
                 keeping the X coordinate of the mouse position about the same.
            2.4) Check that when the Y coordinate of the mouse position is higher than the upper bound of the list
                 then the list continues to scrolls UP and the selected item changes at the top until you reach the topmost item.
                 If not, the test failed. Press FAIL.
            2.5) Check that when the Y coordinate of the mouse position is lower than the lower bound of the list
                 then the list continues to scroll DOWN and the selected item changes at the bottom until you reach the bottommost item.
                 If not, the test failed. Press FAIL.
            -----------------------------------
            3.1) Click on the Multiple List.
            3.2) Press and hold down the left button of the mouse to select (eg) item 5 in the list.
            3.3) Drag the mouse vertically out of the area of the open list,
                 keeping the X coordinate of the mouse position about the same.
            3.4) Check that when the Y coordinate of the mouse is higher than the upper bound of the list
                 that scrolling of the list DOES NOT OCCUR and the selected item IS UNCHANGED at the top.
                 If not, the test failed. Press FAIL.
            3.5) Check that when the Y coordinate of the mouse is below the lower bound of the list
                 that scrolling of the list DOES NOT OCCUR and the selected item IS UNCHANGED at the bottom.
                 If not, the test failed. Press FAIL.
            -----------------------------------
            4) The test has now passed. Press PASS.
