nautilus and wm for gnome
1) Gnome 2.6 seems to act rather counter-intuitively: when i click on Home, i get a folder. I click on a folder inside it and instead of changing to that directory within the same windows, a new nautilus window opens. I have many subdirectories, and soon, my whole screen is filled with Nautilus windows! The only way around this is to browse trees by clicking on the root directory and clicking browse directory. Thereafter, Nautilus will behave sanely.
Is there any better solution than this?
2) How do i change the window manager that Gnome uses? I want to use a lighter one to make it go faster.
