Changing perspective causes popup error, debug perspective no longer functional

Just installed Eclipse Juno, having problems with perspectives since then. In addition to the editor window being very small and confined to one corner of the display (in Debug; it's okay in Java perspective), I am getting errors when changing perspectives. Suggestions? I'm going to go back to Indigo if I can't fix this.

When I switch from the Debug perspective to the Java perspective I get a popup titled "Problem Occurred." The text in the popup reads: An error has occurred. See error log for more details.

org.eclipse.ui.internal.WorkbenchPage.findPerspective(Lorg/eclipse/ui/IPerspectiveDescriptor;)Lorg/eclipse/ui/internal/Perspective;

The error log shows a stacktrace which starts:
!ENTRY org.eclipse.ui.workbench 4 2 2012-11-26 12:56:50.841
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
!STACK 0

Try the steps below:

  1. Start your eclipse with clean option as eclipse -clean. If you are using the shortcut then go to properties and add -clean in the target.

  2. Go to the debug perspective, right click the debug icon in right top corner and select reset.

Hope this fixes your problem.
