Things Disappearing from Login Items?

[xgman]

Has anyone ever had startup programs disappear from the login items preference pane for no apparent reason after reboot? I've had this happen twice over the past year, once in Leopard and once in Snow Leopard. You add some startup apps to the login items in pref pane and reboot and some items are gone and no longer listed in there. Very weird.

The associated file for that is:
/Users/*you*/Library/Preferences/com.apple.loginitems.plist
...in case you want to trash it and start over (it may be corrupt?).
