just checked on my 2K box at work. i have only one sub menu programmes. What is the exact message you get when you try to delete the folders?
you could also go and try the following. right hand click on a clear part of the task bar at the end of the screen.
choose properties in the menu.
on the properties window go to advanced tab.
click on the advanced button. this will ring up an exploer type window.
try to delet the folders from there.
my machine is a 2k pro box so might be a little different;
