What version are you using when this happens?  As of version 1.3.12, I
changed nano's behavior so that suspending it would clear the screen and
put the cursor on the last line before displaying anything, which is
exactly what Pico does.

With nano 1.3.12 or later, at least on my system, the cursor is now
where it was after the "ls /", and any text displayed while suspended
(in this case, the "ps aux" output) is no longer onscreen.  This is what
I think Mike was describing when he said "the resulting terminal state
is as if ps had never been run".

It should be fixed in nano 1.3.12, 1.9.99pre0, and current CVS already. 
If it isn't, please let me know.
