Quite a while ago, I downloaded and installed Safari 4.0 Beta. It began to cause some problems so I deleted the application, but only the application. Since then, I have been using Safari 3.1.2. Now, however, I cannot install Safari 3.2 because "This volume already has a newer version of Safari installed." I think this is because of Safari 4.0, but I cannot fix it. I tried deleting Safari (3.1.2) but that didn't help. Can any one help me?
