Hi Balaji,
Go to the Project menu and deselect the 'Build Automatically' option. This should prevent the above issue. However, you will likely need to run the build manually as without the build, errors may be present but not displayed. When building manually, select only the projects you need to build so that it completes quicker. You can also use this to determine which project has the code that causes the hang.
