Fluxbox is quite an exotic window manager.
Have you tried with an other WM ? xfce or Gnome for instance ?
I have not. This is my first attempt at Fluxbox, but that is because I prefer Blackbox 0.65.x. Unfortunately, there is no more maintance of blackbox, and I really don't have the time to tweak everything anymore. I used to use Blackbox on Gentoo, starting back around 1997 on a 486-66. First those silly people at the phone company tried to tell me that anything slower than a P166 couldn't connect to their ADSL, and later others told me that it was impossible to play episodes of Stargate-SG1 on a 486. Not with Gnome or KDE running on anything, but Blackbox on Gentoo, and nothing else running, I sure as hell could. This computer is new to me, and is probably about four years old, but is still the fastest hardware that has ever entered my home. It could barely move with Windoze XP running on it, but that didn't survive long in my home.
