MBPro won't shut down after Lion upgrade

I upgraded from problem free Snow Leopard to Lion and now my MB pro will not shut down. Just hangs on grey screen with spinning dirvish forever until I force it off with the power button.

No such problem with MB Air I just bought with factory Lion installed.

Anyone else seen this problem?

Make sure you've closed all open windows and applications that you may be using. Also, go into System Preferences, General, and remove the check from the box that states: "Restore windows when quitting..." See if that helps.

Also, the first couple of times when shutting Lion down (especially if have open applications or windows) will take longer.

A thousand thanks to

Chscag. That did it for me. Installed Lion on day one of availability and this issue has been with me daily until I just did as you suggested. I'll have to check the new MB Air settings but that was a factory install and I have had no issues with it thus far.
