Folks, I downloaded 5.1.0r2, unstuffed it, and started the installer up. When the installer was part way through expanding the MacPerl application, it halted. I tried using apple-option-esc, chose shuttting down the installer - and hung the system. My Performa 635 currently has System 7.5.5. I chose the 68k version of MacPerl when I started the install process. I have Ram Doubler running along with Symbionts, the usual Apple extensions - including Applescript, plus TSM Fix, IceT, Internet Config 1.2, MacTCP, and very little else. No Easy Open or Help system. Anyone have a clue about the hang up? Should I try turning all extensions off and see what happens? Should I try choosing a 'universal' version of MacPerl instead of the 68k version? Thanks in advance. Nils Dahl
