recycle bin: delete confirmation dialog

hi,

i want to set up my recycle bin to just delete a file, without storing it. i
just want to select any file, choose delete from the context menu and the
file just disappear for good. i know that selecting properties and checking
the box for 'remove files immediately', removes the files permanently, but i
do not want the system to ask me if i am sure or not, with the confirmation
dialog. on this properties applet, the checkbox for "display delete
confirmation dialog box" is already unchecked and greyed out, after ive also
checked the remove files immediately box. how do i make it so the system
doesnt ask me if i am sure? ive already told it here, on this options applet,
to not ask me, so why is it still asking me anyway?

on this properties page, i have the radio bullet selecting to use one
setting for all drives. below that, the box for 'display delete confirmation
box' is unchecked, then, i have the checkbox ticked for 'do not move files to
recycle bin. remove files immediately when deleted.' once that box is
checked, the area below for displaying the confirmation, greys out, and the
box for that remains unchecked. so, all that i have selected here, should
really not be displaying any confirmation. but it still does. why??
