Well, this is a new one (I think): Win 7 Pro x64. EAV RC. Suddenly (past couple of days) it's taking forever to change the desktop wallpaper in 'Personalization'. Once I have the Personalization window open, changing the background results in a delay of 'several seconds' - enough for the Personalization window to come up with 'Not Responding'. It eventually gets there, but disabling protection in EAV rights the problem immediately.
