Click the "View" button at the top, then click "Text Size" then select what gives you the best fit for the screen. Depending on what size monitor you have, you can also adjust the pixel height and width of the screen. 800 x 600 is good for smaller screens (15"), and for 17" and larger, 1024 x 768 should work best. Adjust this first before adjusting your text size. To adjust, minimize everything, then right click your background, then click "Properties". From there, you will have a "slide knob" or multiple text lines to choose your resolution from.
