I am running the 'eeexubuntu' kernel of XFCE on an Asus EeePC 900. Since I installed the OS, I have had two instances of Pidgin autostart whenever I turn the computer on. I have looked in Start > Settings > Settings Manager > Autostarted Apps, but Pidgin doesn't even show up on there. I can't find anything in Pidgin's own settings menu to control the autostart settings. This isn't a major issue, it's just a bit annoying having to exit one of the open Pidgin windows every time I start up, and finding layman-friendly info about XFCE online is like finding a needle in a haystack. ;oP
