You can start the Eclipse IDE with the consolelog option, this will show you events/errors as they occur on a console, and this could help you understand which areas of the software are affected.
> Open a Visual Cobol command prompt and type:
> cd C:\Program Files\Micro Focus\Visual COBOL\eclipse\ > press enter
> then type:
> eclipse.exe -consolelog > press enter
You will see a console window open up and in there what Eclipse is loading/doing.
