No Idea on the CPU useage, but I havn't psyched myself up yet to download the iso's for F10 on dialup, so don't have it installed yet to try to recreate your problem. 6 cd iso's for F9 was bad enough, and I'm still recovering from 14/15 days of downloading them on dialup, with frequent pausing of Kget, so as to retrieve mail, etc. Nigel. -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
