FC4 is awesome OK...faster..but still is little unstable!! Opening mplayer sometimes hangs the OS.After that when I reset manually it hangs on "Enabling swap partition", then I have to again reset. After that it works fine untill the the next mplayer execution! By the way Mplayer hangs 50% of the time not always. Also after clicking application menu, the menu appears after aprox. 3 s, when clicked first after the OS bootup, after that menu appears fine! Does anybody experienced similar problem or know a way to deal with it??
