Sounds like you're on Windows, so it's probably this bug:

I am on Windows. It looks like my programs are running editline or
something to give a command history. Ordinarily that would actually be
quite useful, but for this particular application, not so much.
Although: if you're trying to get at the arrow keys from the Windows
cmd console, it's not possible by reading stdin; rather, you need to
access the lower-level Win32 console APIs:

Not sure if it will help, but you could take a look at what I did in Haskeline:

All useful ideas. I'll give that a shot...
