I have an issue pertaining to admin permissions and read-only files. It seems all my files and folders are read only, and when I remove read only it automatically reverts back to read only when I check again. I am administrator with full privileges. Sometimes I get a prompt saying 'i need admin privileges to change a file' even though I'm logged in as admin. It seems on my local c drive, despite the read-only status of files, I can still modify them, but when I try to modify files on my external harddrive, I can't. I have to save as a new file. It's so frusterating! With the external hard-drive, I think it has something to do with having reformatted my C drive. any thoughts on this?
