On my Mac OS X 10.5.7 system I've installed and uninstalled GasMask (a utility to manage hosts files) at some point. Ever since then, when I manually edit my hosts file (which I furthermore manually recreated after uninstalling GasMask) the changes don't persist when I reboot the machine. Any idea what is going on here?
Furthermore, what steps could I undertake to revert to the vanilla state from before I had GasMask installed? I think some config changes from this GasMask installation might be the root of my current problem.
