Error "java.lang.NullPointerException" while adding variable in CCX editor Installed in Windows 7

few days back i was getting a weird behaviour from the instance of the installation of CCX editor(version 9.x) installed in my window 7 machine.
Every time i try to add a variable it is giving me a java error "java.lang.NullPointerException " . After going some google found a cisco post which explain the issue with new version of windows with CCX editor 7.x .

Here is the error i was getting

Resolution to this is as folows"

1. Right click on the icon for CRS editior

2. Go to Compatibility and choose run as windows 2000

Now try to re-launch the CCX/CRS editor and the above error should not re appear again...
