So, I was about ready to give Westlaw some credit, for having a nice printing feature that remembers what settings you used last time (which is better than some apps I could name). Very nice.
Then I tried to upload a file. Westlaw happily checks the file path and lets me know that / is not a valid character in a file name. !@#@!#@!#. [Unix-using users will know that effectively all file names in Unix systems include /. This is why webpages have //// and not \\\\\ in them.]
