Ok. As far as the padlock, I would almost bet it is hidden under the widgets. To verify that, just go to Desktop PWigits on the menu and remove all the wigits and click apply.
After, if you see your lock icon, move it away from the wigit area.
As to the shutdown problem, add a parameter to your menu.lst of acpi=force and your computer should power off when you select shutdown from the submenu.
PS: Opps did not comprehend your meaning on the padlock. I thought you meant the desktop locking padlock.
