This should probably go into the question about Windows Annoyances, but can anyone explain why this happens, and how to fix it?
I right-click on a folder, select properties, and uncheck the Read-only. Click on OK. I get a confirmation with the option to apply changes to this folder only, or include subfolders and files. I select the latter, and click OK.
Go back to properties, and it's still showing up as Read only. Why? I can't see any files that are still read-only
