Hi Matthew If I understand well just to have rfp in system crash your GS? Even before you use it by Finder ExtraMenu? Can you give me more details? (GS rom 1 or 3, GS/OS version, RamFAST version, etc...) Thanks PS: If anybody have same problem or not please say it ;-) Babar de Saint Cyr (France) Apple 2e, Apple 2c, Apple 2gs, Apple 3, Apple 4, App... ^H^H^H^H ;-)
