I always like selecting new tools. But as Lindy has shown, sometimes you find a bad one. There's other tools that let you gracefully recover, with a bit of planning and habit changing. Try virtualisation. I keep one system that is rarely changed, and several virtual systems for experiments. These can be easily reset back to how they were before any accident of excessive trust. I won't recommend any particular virtualisation software, because I've used so few of them, and your needs will vary. But you can find a reasonable list of them here: http://en.wikipedia.org/wiki/Comparison_of_platform_virtual_machines --=20 James Cameron http://quozl.linux.org.au/ --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
