Select Reference Without Clicking

If I’m working in Endnote X2–things going well–then I go to Word or some other document.  When I come back to Endnote, instead of the reference I was working with being highlighted in blue so that I can edit it or arrow to a different reference, the reference is highlighted in grey.  The only way that I can edit again is by clicking on it. 

This also happens when I create a new reference, ctrl+w to save/close it.  I then want to edit it because invariably I forgot something, but again it is only grey highlighted so I have to click on it to open it. 

Okay, so I’m lazy, but I just like to interupt my keyboard use if it’s unnecessary.  How do I get it to stay ‘focused’?
