I've since uninstalled the Microsoft Search Toolbar but it hasn't helped. I've no idea what program may be putting a lock on these directories. I can't delete it even if the directory is empty. If I reboot, I can sometimes remove the offending folder. Something keeps setting the Read Only flag in the permissions. I clear it and it comes right back.
This is maddening. I can't keep track of what directories actually have something in them or not.
Thanks to any and all who may be able to help.
