I just discovered that if I have a ruby program that uses "Dir.getwd" to get the current working directory, I get different results from 180-10 and 181-11 and I wanted to know if any of you can duplicate this, or is there something weird with my machine. In 180-10 I get: E:/Dev/RubyDev/rubyinstaller/cvs-repo/installer/builder while in 181-11 I get: /cygdrive/e/Dev/RubyDev/rubyinstaller/cvs-repo/installer/builder Does this mean that 181-11 is really a cygwin-based build instead of a vc++ based build? Do any of you get the same behavior when comparing these two versions? Thanks, Curt
