Thanks Matthew! In retrospect, I guess I'm used to the occasional readline issues on OS X and Linux in the past, so part of me is assuming that Windows works the same. Also the documentation for Racket isn't as verbose as some of the documentation I read, so I need to parse it better.

Readline isn't useful when using "cmd.exe" in Windows, because the Windows command shell gives you readline-like functionality automatically. There's a note to that effect before the `install-readline!' example in "More", but maybe it needs to be more clear that readline typically isn't available at all under Windows. So, I think you want to just remove the `readline' loading from your "racketrc.rktl". </div></div> </div> </body></html>
