Since the issue of the 0.11.0 version, it appears that the Alt+O is a real concern to many users using Windows (Vista or Seven) :
I found a trick that makes the Alt+O active :
1) open Stellarium
2) reduce it by pressing F11
3) maximize the window using the Windows square icon on the top right corner of the Stellarium window.
=> then Alt+O will be active.
Some users have said that disabling the advanced key setting (in the Region and langage setting configuration panel) may fix the issue.
