Ive noticed that too on fedora abd Kubuntu, but not xubuntu or Mepis<BR>It goes away if you remove all netscape based applications and librarys<BR>
They act like a fresh install!...sometimes :P<BR>
For some reson that dosent happen at all when running Fedora on a virtual pc under<BR>
windows, is this because the ram is still managed by windows?<BR>
