I have the same problem with the combination above with Ruby 1.9.2 on Windows XP, as described here: http://www.ruby-forum.com/topic/205569 Calling Rspec directly produces colored output, but autotest spits out ANSI sequences. The issue was supposed to be closed with win32console 1.3.0, but obviously it didn''t for the above-mentioned combination. -- Posted via http://www.ruby-forum.com/.
