Aye I've noticed minor issues like that too sometimes, generally easily sorted though with a bit of fiddling:O Another Arch user!!!! I love Arch! I really do But I haven't had the success you've had with stability. For some of it, it's because I'm using AUR. But then I run into other issues and dependencies that won't go away. ldconfig was complaining after every pacman call about having 2 links pointing to the same .so file while being a different type. And I still have not had the same success with wine and some windows apps that I had on my ubuntu partition. But yes, Arch + KDE 4 is the nicest thing I've come across in a while My own stability issues aside, I still love it
Have had far worse in Fedora (which used to be my distro of choice) however, and I imagine other distros aren't much better if you run a wide variety of software that isn't straight out of the repos (another thing I like about Arch is pretty much anything will at least be in the AUR).
