Tom, I had similar problems - a member of this list suggested reinstalling from CD and then using the combined upgrade to the most recent version. This I did and it cleared my problems. David.

When I try to open mail, it just sits in the dock...no window, nothing, and I have to force quit to shut it down. There is also a bookmark problem. When I try to save a bookmark (safari, etc.) it fails the first time and I must do it twice. Then I have two bookmarks. It also often fails to open a new page and I have to do that twice. It works fine in Jaguar. Any ideas would be appreciated. _______________________________________________ Cube mailing list Cube at listserver.themacintoshguy.com http://listserver.themacintoshguy.com/mailman/listinfo/cube
