Question Title How do I resolve the error "Unhandled event loop exception"?

Question:

When I attempt to run my program nothing happens, but I notice the following error in the Error Log view:

Message                          Plug-in
------------------------------   --------------
Unhandled event loop exception   org.eclipse.ui
and when I open the error log I see:
!ENTRY org.eclipse.ui 4 0 2010-11-09 16:44:55.197
!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.NoClassDefFoundError: com/iscobol/rts/IscobolClass
        ...
	at com.iscobol.plugins.editor.launch.IscobolLaunchConfigurationDelegate.doExecute(IscobolLaunchConfigurationDelegate.java:216)

Answer:

This error occurs when the "Default isCOBOL Runtime build" is set to an invalid path or filename.

To correct this error, select Preferences from the Window menu and click on the isCOBOL node in the tree. Set the "Default isCOBOL Runtime build" field to a valid path and file name or clear the field's value to allow the IDE to use the isCOBOL runtime build included with the IDE.
