[OpenIndiana-discuss] Gnome desktop system commands don't work?

[Dan Swartzendruber]

I did google for this extensively, but only found things that don't 
quite match. So I have a brand-new oi151a7 install with gnome desktop.  
So I click on System => Administration => Users & Groups, expecting to 
get a prompt for password.  In the margin at the bottom of the screen I 
can see 'Starting Users & Groups', followed a few seconds later by... 
nothing?  I have found related complaints where the user is prompted but 
their password is rejected.  I get no prompt at all - it's like I never 
tried.  Not just that command - tried several others off of System, with 
equal (lack of) success.  I'm not that experienced in gnome so this is 
probably something silly, but what?
