Session Drummer 3 Question

Hi everyone. I'm brand new to Sonar X3 so forgive me for any stupid questions.
 
I'm assuming that there's a very simple answer to this question but I can't figure it out.
 
I was working on a project where I loaded session drummer 3 and a couple of audio tracks. After I finished laying down the drum parts, I closed off session drummer. Now I've re-opened the project and want to do more with the drums but I can't figure out how to bring back the session drummer display. How do I get back into session drummer?
 
Thanks.

Thanks. I was just coming back to post that I got it figured out.

Ditto what Keni said, that's how I have always done it. There's a tiny little icon in your soft synth track that opens the GUI. This must go back to the beginning of Cakewalk history. 
And just so you know, You don't need the GUI open once you've selected your sounds. If you have 2 monitors you can toss it over there, that's what I do now.
