If you install ClarisWorks for Windows 1.0v1 with ATM turned on, it is possible that Arial will not be available in the font menu even though it is still the default font.
When you install ClarisWorks, it creates the font by taking the first 22 fonts in the system. It is possible that Arial will not be among them.
1. Choose Other... from the Font menu and manually add Arial by clicking the Add to Menu checkbox.
2. Turn ATM off before installing ClarisWorks for Windows.
