Win XP Sp2. Control Panel ->display->Customize desktop: desktop icons ( My Network Places, Internet Explorer, My Documents all left unchecked . Desktop screen looks OK (only wanted icons). On the right hand side of the taskbar I have Desktop >>. When clicking on >> Desktop items appear , all wanted icons PLUS My Network Places, Internet Explorere, My Documents. No matter how many times I try to get rid of them (right click delete, "are you sure you want to remove.... from your desktop .." ) , they temporarily move to the bottom of the column. I only noticed this recently, (at one stage I simply noticed that I have a lot of items on the desktop, after cleaning the majority of them I noticed this peculiar problem) . It could have started after SP2, I don?t know.
