Summary: select none causes monitors to disappear

Initial Comment:
hi,

using the latest CVS build, 

monitor [num1] [num2]
select none

causes the monitor to disappear.  selecting any set that contains the 
two atoms shows the monitor again.  I think this is a bug; monitor 
visibilty should not be controlled by simple selection.

er, I've narrowed it down a bit, and gotten a bit more confused at the same 
time ;-).

this only happens when a monitor is drawn between two alpha carbons of a 
backbone/cartoon shape.  I think we spoke about this issue a while ago - 
monitors between atoms that aren't rendered.  IIRC you convinced me that 
the endpoints must be rendered in order to draw a monitor, and that is still 
acceptable.  AFAICT this is just a strange side effect.

if I send this script to the JmolApplet, assuming atoms 1 and 2 are alpha 
carbons:

restrict none
select all
backbone 0.3

set monitors off
set monitors 0.2
color monitors white

select none
set display selected
select atomno=1,atomno=2
monitor 1 2
delay 2.0

select none


the monitor line appears, and two seconds later disappears.  if I go back 
and issue a 'select all' via the Console, the monitor comes back. I can toggle 
the visibility of this monitor using select none/all commands *as long as set 
display selected is true.*  if I set display normal, no monitor.

I confirmed this in Jmol.app.  same behavior - I can toggle the monitor line 
even when the endpoints are not rendered by issuing 'set display selected' 
and 'select all' or any set that includes either endpoint (does not have to be 
both).

some kind of short-circuit between set display and monitors/measurements 
perhaps?

I don't think this is a crucial issue.  I can certainly get around it easily 
enough.  in the meantime, I'll look into whether or not the set display code is 
interacting with monitors at all.
