Screen savers created with the Toolbox will only run on Windows 95, 98 and NT. We also recommend that the computers have at least 16 MB of RAM; 32 MB would make it run even better. The processor should be at least a i486 or equivalent. Also, for the end users to see the best quality, their Display Properties - Colors should be set to at least 256 colors if not 16 bit or higher.
