WotLK Resolution settings unable to be changed

[Phakey]

Not sure how to get my resolution settings to stay put after i log out. Everytime I log in the settings have reverted back to huge screen and loud sound. I have tried unclicking the "read only" in the properties-but the button keeps getting checked again. Not sure what to do from this point. Thanks.

Follow these steps:
1) Restart your PC
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only"

if it does not work, try this:
1. copy your "WoW" folder on your desktop
2. delete your old folder
3. do "read-only" stuff on this new fodler placed on Desktop
4. play with this new folder
