org.eclipse.swt.SWTException: “Widget is disposed” when trying to open AndroidManifest.xml

I am running Windows 8 and using Eclipse Kepler Release to create android application.

When I click on the AndroidManifest.xml file in my project, I receive an alert which shows the following error message:

Problems occurred when invoking code from plug-in: "org.eclipse.e4.ui.workbench.swt".
