OK. I've just got my new ARMiniX to play with. But once I've managed to
overcome the urge to experiment with that I'll do so...

Erm... I've reported both before (in more than email here). See for example
emails from 27, 28, 30 Mar 2012 and 2 Apr 2012. So I guess they have been
forgotten. But I'll summarise again below...

Choosing the shutdown on the switcher menu. This pops up the usual choice
with a shutdown button. Clicking on this makes the icon go to the
'depressed' state. Then nothing else happens. No shutdown.

The CPU use goes to 100 percent and stays there.

I then close down the Xfce desktop window by clicking on its close icon.

So far as I can see (and from the discussions we had back when) this is
quite safe. Just odd.

As above. The RPEmu 'screen' shows the shutdown icon in the depressed
(shaded) state but then no progress.

I have a vague recollection that I once did a screengrab to show what the
RPC 'screen' looked like when frozen and put it on the web. If I get a
chance I'll do that again to show what I get.

The roller skates effect is hard to describe in detail. But the behaviour
means that if I move the mouse and then stop it, the pointer keeps rolling
for a while as it glides to a halt. Its as if moving the mouse whizzed up
some spinning 'inertia wheels' inside the mouse that keep things moving as
they run down when I stop the mouse. Bit like trying to walk on ice.

OK. Again this isn't really a problem. I just mentioned it for completeness

Of the above, the roller skating effect is the most bother as I have to
move the mouse around with particular care. But not exactly a serious
problem, more of an oddity I have to keep in mind. However I'd have to
video the desktop to show what it is like!

OK. Thanks. That's what I suspected. But wondered if there was a particular
advantage for 5.1x. I'll stick with 4.02.

I'll try 0.8.10 with 4.02 once I've got the ARMiniX sorted. Then report
again to say if I get the above quirks or they vanish.
