WinGHCi won't start

Question

So, I tried to ":set prompt "λ> "" in WinGHCi, it crashed and after that wouldn't start again (Not Responding). I reinstalled the Haskell Platform and it still won't start (Not Responding). GHCi works in cmd. I searched for remaining .conf files before the first un/reinstall for WinGHCi that could make it crash but couldn't find any. I'll appreciate any help, thanks in advance.

Answer 1

WinGHCi stores its command history in the registry. Just delete everything under HKEY_CURRENT_USER\SOFTWARE\Haskell\WinGHCi from the registry (use regedit).

Additionally, please report this to the developer.
