[Haskell-cafe] Darcs 2.2.0 diff on Windows

When using this inside the Windows command prompt (CMD.EXE) I get darcs: diff: runInteractiveProcess: does not exist (No such file or directory) It works fine under MSYS. Also when using --diff-command to launch a GUI diff tool, Darcs does not seem to copy any changes the GUI tool did to the "new-program". Is this intended behavior?
