I just upgraded, and for the most part everything works well. But the Dock seems to have some problems. Usually I can open force quit and restart the finder, then the dock resets itself. But it doesn't do this in Leopard. Also, when I quit a program, the dock still has the little "light" below it signaling that it's open. When I click the icon it goes away. But the biggest problem is sometimes, is doesn't who any programs as being open, nor does it respond to any clicking. Any ideas? I searched the forum and didn't see any fix or report of this problem. My guess is that some programs I have aren't fully updated to Leopard yet (ie. Azureus or Popcorn beta). Thanks!!
