when I tried to boot back up into Sugar, I got a blank screen. The culprit is olpc-kbdshim.i686 0:18-1.fc14. When you did 'yum -y update', it got picked up. You should have done 'yum -y update --exclude=olpc-kbdshim' One bypass might be to download olpc-kbdshim.i686 0:17-1.fc14, then at the

Does that mean that with FF4 installed, Browse is still working because it is (equivalently) using FF3.6 as the backend? Would that mean that if we were to upgrade to FF4, we would have a disparity in rendering between GNOME and Sugar? A note from a sometimes_bleeding_edge user: Ever since
