I routinely get this console message after an office app (mainly Outlook) hangs:

11/17/12 10:40:18.094 AM WindowServer[87]: reenable_update_for_connection: UI updates were finally reenabled by application "Microsoft Outlook" after 15.51 seconds (server forcibly re-enabled them after 1.00 seconds)

I have installed the most-recent Office update 14.2.5 and all Apple update.

Thoughts?
