This crash is really predictable. My server runs FC3 and it's all fully up to date on XFCE4 desktop. I installed aMule with Synaptic if that matters. The server rings out on my dialup modem. I VNC into the server to have a look and see how things are going every now and then. If I leave the XFCE desktop that is showing aMule with the focus when I exit VNC, by the next morning aMule has shut down every time. If I move the focus to another desktop so you can't see aMule it's still running fine the next morn.. I don't need any urgent help as I can just move the focus when I exit VNC and alls well.
