[O] Problems with Agenda view in org-mode

[Florian Faul]

Hello dear developers of org mode,

I ran into a problem using the agenda view with org. When I turn on the agenda view I want to see the different levels of next such as in 

NEXT Do that
. NEXT Do this 
.. NEXT do this now

This is the way it works on my Linux OS

however, using Windows 7 I don't see the different levels. There is only one level, such as:

NEXT Do that
NEXT Do this.

NEXT do this now

Is there a way to get the "Linux" view on the agenda?

Thanks in advance!
