I often use screen-share from my laptop to access my Mac Pro desktop to perform simple tasks without actually going upstairs to access the computer. I have the desktop intitiate the screensaver with a lock screen to prevent access automatically after 10 minutes of inactivitity. However, after upgrading to OS 10.8.2 the screen saver no longer functions after using screen-share. It continues to "not" work even after ending my screen-share session and closing my laptop.
I have to re-start the desktop for the screen saver lock to function again (making it fairly useless). Any ideas how to correct this problem, or is this just a new Mountain Lion "feature."
