Overview grid / Instant Expose / Single desktop expose don’t work ;
Works only selecting desktop from the menu bar.
And screen blinks (black background / background image) - it lasts about a second. During the blink there is beachball on TotalSpaces’ icon in menu bar.
Usually after a few minutes of “blinking” and “not working” - TotalSpaces2 starts to work and until the next restart everything works fine.
