Hi trout00
You have a couple different options for changing the font size of the message box. The first option is to change the native Windows message box settings. From Windows XP, right-click on your desktop and go to "Properties". Click on the "Appearance" tab in the Display Properties dialog box, and click on the "Advanced" button. In the Advanced Appearance dialog box, select "Message Box" from the "Item" drop-down menu. This will allow you to change the font of the message box text.
Your other option is to use a custom step type. This
KnowledgeBase has more information on this option, including a link to an example program.
