When initially set up, the window size is rather small, as shown in the top full-screen shot opposite. However, it is possible to alter the font used to increase the window size.
With Pedigree running, right click on the top bar of the window and choose Properties. Then select the font tab, where you can select both font and size, as shown below. The small window in the Properties tab shows how the result will fit on you screen. The final selection shown gives an almost full-width window, as displayed in the lower full-screen shot opposite. Click on OK to confirm your choice, then choose all similar windows to finish.
