Sorry, i raised an issue earlier (#197) which you said was fixed in 1.9.6, so i upgraded and now get this. Apologies if I've done something stupid along the way :)

Atom: 1.14.4 x64
Electron: 1.3.13
OS: Mac OS X 10.11.6
Thrown From: ide-haskell package 1.9.6

Uh... did you restart Atom after updating? It usually wants you to...

commented

I'm pretty sure this can only happen if ide-haskell goes away (disabled, removed or updated) with repl open...

commented

Yeah i restarted. I've just been using ghci through Term3 today (i.e. no repl) and have not seen the issue

commented

So... you closed the issue. Did it "fix itself" or do you have other reasons?
