It's a problem with buffering:

hSetBuffering stdin NoBuffering

This usually doesn't work on Windows:

GHC 6.4.2 and 6.6: requires <enter> Hugs (console) Sept. 2006: requires <enter> WinHugs (GUI) Sept. 2006: works as expected

But it seems to work on Linux: GHC 6.4.1 on Ubuntu 6.06: works as expected GHC 6.6 on Ubuntu 6.06: works as expected

I am really interested in hearing of a solution that works on all platforms.

Does 'readKey', from System.Console.Readline, works on Windows? It works on Linux with the buffering advice applied. Maurício
