[Haskell-beginners] Compiling Test.hs from reactive-fieldtrip

[Nathan Huesken]

Hey,

Thanks, it compiles now.
But when I run it, I get a empty window not updating itself ...

Does the Test.hs from reactive-fieldtrip run correctly anywhere else?

Is reactive-fieldtrip up to date or is it outdated? (The last update is
May 2009 ...).

Regards,
Nathan
