I have been on Lion for about a week now on my iMac and noticed an odd behavior. When I open an app it no longer appears in the doc, and if it was in the doc already, it no longer has the little arrow under it to say it is open. This is not happening with ever app, for example Chrome, and terminal both have arrows under them, but MS Word does not. Calabri, Yahoo, and other apps do not even show in the doc no matter if they are running or not. They all show in mission control fine. How do I get the Dock working again? Thanks!
