Windows 7 - Netflix Movie Streaming - How to Get Back to Browsing?

I am new to WMC and I linked my netflix account to it. While I like the fact that WMC integrates my media experience, I am very disappointed that the Netflix streaming does not have a good exit. Everytime I choose a movie to watch, it's OK, but at the end of the movie, I get a black screen. No Exit, No way to get back to the Browsing Window. Nothing. I have to Ctrl-Alt-Delete, restart WMC, and get back to Netflix. Surely, there's a better way to end the movie?

Just press the back button.
Top left of the screen. Its hidden until you move the mouse.

Actually, I played a show for my daughter (Dora the Explorer) and at the end the program successfully returned me to the Browsing window. Tried with one of the TV shows I am watching these days (Medium), and it got stuck again. There's no back button at all. The mouse does not activate anything. Basically, it's frozen. So at this point I have to conclude that the problem may be with some select shows. I guess I will have to watch Medium in the IE browser until a solution exists.
