CGXDisableUpdate slows me down

I moved to ML recently and getting so many problems. One is thsi;

1/2/13 9:09:06.789 PM WindowServer[99]: CGXDisableUpdate: UI updates were forcibly disabled by application "Finder" for over 1.00 seconds. Server has re-enabled them.

1/2/13 9:09:10.940 PM WindowServer[99]: reenable_update_for_connection: UI updates were finally reenabled by application "Finder" after 5.15 seconds (server forcibly re-enabled them after 1.00 seconds)

Whatever I am doing is stopped, SBBOD and then 5 seconds later, tis fine. Thought the move to a dual cpu Mac pro would stop this crap, now it's still there.

Any suggestions of how I can stop this?

There are so many little things causing SBBOD, including
