I have the same problem in this thread on the Apple support website:
http://discussions.apple.com/thread.jspa?messageID=10821012
The only solution suggested was to reinstall the os. Does anyone have any ideas?
"I'd be using firefox with no problems.
I'd go to load a page, and firefox would get stuck trying to resolve a host name (implying DNS wasn't working, at best).
I'd click on the airport menu item, but the menu wouldn't open.
I'd move the mouse cursor off the menu bar.
When I move the mouse cursor back over the menu bar, I'd see the beachball.
All finder windows get the beachball.
Killing the finder did nothing; wouldn't fully die or restart.
I'd have to hard-reset the machine to recover."
