In Horizon, every user has the ability to set the font type and font size for the screen. However unless you use the recommended standard font, some Horizon buttons and options may fail to appear correctly on the screen. Follow the instructions below to avoid this problem.
From the Horizon log in screen enter your username and password, then select the Options button. The following window appears. The recommended standard is Arial Unicode MS with a 10, 11 or 12 font size. Be sure to check mark the "Make Default" box to save these settings.
