upgrading to Sequoia caused the dock, wallpaper, and screensaver to stop when waking from sleep until something triggers after five to ten minutes unless I restart. it's driving me bananas. I don't want to downgrade because I don't have a backup and I've had my computer set up just the way I like it for a while now. but I'm on the verge of downgrading anyway. has anybody else gotten this bug and know the fix? software possibly involved: aerials, johns background switcher, mac's dock.
