When I use Windows, I spend a lot of time in terminal windows. If it's SSH to some other machine, there are quite a few options, and I'm actually quite ok even with putty. But when I start a cygwin shell, it gets started in this wrapper app called 'mintty'. And I don't like it, or rather, I don't like the combination of it with the Cygwin terminal emulation. It responds slowly; and sometimes the last line gets garbled (especially if I use a long / multi-line command), and feels a lot less snappier then shell sessions on other machines.
So I'd like something else. I hope it's just mintty that I need to replace, although it may go deeper or it may be the case that there's nothing I can do.
