Last week I installed RC2.3, and while it looked a lot better than RC2 I still have some issues with it.
This is the second installation where I just 'lost' the Xfce Desktop after a while (same thing happened on RC2); I boot the computer and login as my everyday user, only to be greeted by a panel without a 'running' desktop. I can still open programs from the menu, but they don't show up on the panel and apparently they can't be moved either. I haven't yet located the correct command to start the desktop myself.
While the 'Session' menu lists both Awesome and Fluxbox neither wants to be booted; Fluxbox doesn't seem to be installed, awesome is though. With a new user, XFCE looks alright, though I guess it's just a matter of time before XFCE is b0rken there too.
