EndNote XX: Copying on-line found refs to open local library

In EndNote XX, after finding a reference on-line, I can only add it ( ‘Add Reference To’) to one of the existing groups I created in my library. If I try using the alternative, ‘Copy Reference To’, there is no option of copying the reference to already open library without specifying the group - I can only copy it to a new library or a different to the one that is open. So, my question - how can I copy a found on-line reference to an open library without assigning it to a group?

 It looks like just ‘Copy’ in the search list; going to ‘All References’; Paste - works… But why the name of the library is not in the pull down menu as soon as I click ‘Copy Reference to’? It was awailable in the older versions!
