New description:

 Behavior:

 When a compiled haskell executable launches into a windows 7 `cmd.exe`
 terminal session, it does not respect the users `quick edit mode` setting,
 and launches with the system default setting instead.

 I have not replicated this issue on other versions of windows.

 Details:
 For a description of the feature behavior, see:
 https://blogs.msdn.microsoft.com/adioltean/2004/12/27/useful-copypaste-
 trick-in-cmd-exe/

 The registry key entry controlling this setting is:
 `HKEY_CURRENT_USER\Console\QuickEdit` (1 == on, 0 ==off)

 Tiny illustrative program:

 {{{
 main :: IO ()
 main = putStrLn "Try to copy this text" >>=(\_ -> getLine) >>= putStrLn
 }}}

 Additional notes:

 The workaround is pretty simple, launch the program from a `.bat` script -

 {{{
 cmd /K myscript.exe
 }}}

 Or from inside an existing `cmd.exe` session, and the problem goes away.

 Thanks for the report, I'll look into this soon.
