I start the executable (after building it with cabal) and it says "Application launched, listening on port 3000." Next I connect to it with my web browser and the console says "threadWaitRead requires -threaded on Windows, or use System.IO.hWaitForInput." The web browser never connects. Not sure what this is actually recommending I do to resolve the problem.
