I cannot help much with this.
From
http://chemapps.stolaf.edu/jmol/docs/#connect
it seems that you might need to specify "opaque" or "ModifyOrCreate" options 
for this to 
work.

You get a helix if there is a HELIX record in the PDB file, specifying the 
residue range.

Alternatively, you may try "calculate structure" -- but that will likely nedd 
proper identification 
of Calpha and so on, not sure.

There is also a rather undocumented feature in Jmol by which you can force a 
helix or 
sheet, using "calculate" command I think. I think this was described in a 
recent post in the 
email list, cannot find it now.  Hey, there it is clearly documented!

That's  "structure helix" !!

This is why I love Jmol...

Not the last created bond, but all bonds in the currently selected atom set.

There has been some redesign recently in the signed applet for this, so it may 
be that. 
If you get no answer from Bob, please open a bug report.

This is a perfect place. It could have gone into the developers list, but all 
users may benefit 
from the problems and the replies.
