You can change the height and width of the squares where the dates are displayed in a number of ways by using your mouse. If you use your mouse to point to any vertical line in the calendar, the mouse pointer changes to a double-headed arrow. Drag left or right to narrow or widen the column. Likewise, if you point to a horizontal line, the mouse pointer again changes to a double-headed arrow, indicating that you can drag up or down to make the date box taller or shorter (see Figure 20.18). This is particularly useful when you have more tasks on a given day than can be displayed at once.
