I've got a PowerMac 7200/75, running System 7.5.5. While in MPW (3.4), if I attempt to cause ToolServer (1.1.1) to run, say, 'rshell -b "perl -v"' (either MacPerl MPW tool version 5.0.7r1m or 5.1.0r2), my computer has hard hung. (The mouse stops, Cmd-Ctrl-Power has no effect, and I force myself to press the power switch on the front.) Am I doing something wrong? I didn't find any reference in the documentation to failures under Toolserver. Sincerely, Richard Yeh
