*** Issue 150569 has been marked as a duplicate of this issue. ***

Rajiv,

When you say de-select the newly created 'unnamed' group, what do you mean by that? select another group?
Secondly, whenever no group is selected (in the case you open the window for first time), the 'Edit Group' button stays
disabled. In your setup, does the button remain enabled even if no groups are selected? Think, it may be getting enabled
for fraction of seconds before getting disabled, in your setup, is it so?
Please clarify on this.

Thanks,
Sujit

>>>When you say de-select the newly created 'unnamed' group, what do you mean by that? select another group?
1)Not to select another group you just press the CTRL key and select the 'unnamed' group which will de-select the newly 
created 'unnamed' group

>>>Secondly, whenever no group is selected (in the case you open the window for first time), the 'Edit Group' button 
stays
disabled. In your setup, does the button remain enabled even if no groups are selected? 
2)yes , whenever no group is selected (in the case you open the window for first time), the 'Edit Group' button stays
disabled and even you had a group n the case you open the window for first time the button is disabled and it is valid.

hope this helps Sujit :-)

Thanks Rajiv for the additional inputs. The issue has been resolved.
