This is tripping me up a little, because of course the commands are mostly bred into my fingertips, and it's a difficult adjustment. I hit return, and I see a folder that contains the "child" folder "../". Is this a glitch in mutt's handling of information that I ought to report to mutt maintainers?

Hi all! I read that the older Nvidia hardware (maybe < GF8) is in a different driver and no longer maintained. Is that the case? I have a GeForce 4000 MX that I'm trying to get to work on debian/sparc64, which I admit is a bit of longshot, but I was wondering how much effort it would take to even get the driver to build, and then to function. I'm very proficient in C but don't have
