I just upgraded a user from Windows 2000 to Windows XP professional. Everytime I create a file on the disk (C: drive) the file is created as a read-only file and I cannot write to this file. I have admin privledges on my user id; but once I go to properties and uncheck the read-only box, hit apply, and OK, I than go back into the properties and the read-only is still there. What is the deal?
