Suddenly FF browser disappears off desktop when I click on another imac app in the dock. The reverse happens to the other apps when I click FF icon. ???
FF is acting like an independent iMac app and disappears when I reactivate any other iMac app on the dock. When this happens all other active iMac apps except FF appear overlaying each other according to previous activity. When I again click on FF in the dock, ALL other active iMac apps disappear off the desktop and FF reappears by itself along with all of its open FF windows.
Why isn't FF being pushed down and overlayed on the desktop just like any other iMac when another app is activated instead of totally disappearing and then popping up to the top on the desktop when FF is again clicked in the dock without maing all other inactive apps disappear totally off of the desktop????????
