MacBook Air forgetting display arrangement My Mac seems to be forgetting display arrangements for external monitors. It doesn't matter what type of connector it is (Tried Apple converter to VGA as well as non-apple to DVI). Within only a few hours after unplugging the display it will be reset.

Has anyone seen anything about similar issues? Is it maybe Mavericks-related?
Deleting /Library/Preferences/com.apple.windowserver.plist as well as all files in ~/Library/Preferences/ByHost which began with com.apple.windowserver seems to have fixed the issue.
