Okay so i tried reinstalling everything from scratch including mushclient and i followed the instructions step by step. still having this double prompt issue.
i cannot figure it out for the life of me.

I'm on windows 7 i don't think that would be an issue but i figured i should mention anyways

Edit: I fixed it, somehow, I don't know how. But it stopped doing the cutoff problem (still look like a double prompt but it's not AlWAYS there now)
