If you are going to edit Unix files from Windows, I recommend Emacs, which gracefully handles the line ending issue.
It doesn't sound like Douillard actually wants to run dotLRN on Windows, but since Don brings it up... Win32 support should be going into the AOLserver 4 branch soon, but probably after the next beta release is tagged. I've also sent the ACT information on the AD13 commands 4.0 needs to fully support OpenACS. I don't expect those in the upcoming beta either, but presumably for 4.0 final.
