How to play in the window-mode?

Hi guys,

first: Sorry for my english, I'm german.


But I've got a question:
How can I play in the window-mode?

I tried it, like I did with Pro Evolution Soccer, but nothing happened, and now I don't know, what to do, because I better like playing in the window-mode.
I hope you've got some advice for me.

i think you cannot play in a window mode in nba live
