Wonderful with fast download servers - downloaded both the Fluxbox beta and Debian alfa in a matter of minutes
I have so far run it in Virtualbox - of course not the best way to get the feel of speed, but I've got a reasonably fast computer (Athlon 64 3700+ and 2 GB memory)
Just before the desktop appeared there was some odd artifact - the words Fluxbox and Mint in some grey foreground.
/Edit/ It's the splash in some distorted way //Edit again/Has to do with Virtualbox I got the same with Daryna standard gnome live CD i Virtualbox
And I don't find the menu.... This can be ignorance on my side about fluxbox, but anyway
/Edit/ Indeed it was - right click the desktop
Very nice start up music!
Have to do some more testing....
