saving a reusing session

Hi all.

I'm completely baffled by JSwat sessions.  I thought maybe my 1.5.10 version
was just misbehaving, so I switched to 2.4 but I still don't get it.  Is
there some documentation I'm missing?

Here are some things that puzzle me:

How do I save a session?  There are options to open, copy, and delete
sessions, but not to save one.  The best I can do is set the current session
to be how I want and copy it under a new name.

How do I save classpath info in a session?  Without seeing any docs on the
subject, my uneducated guess is that a session includes the stuff in the the
"Start VM" dialog, the classpath, and the source path.  However no matter
what I do the classpath resets to tools.jar and bootstrap.jar.  Is that by
design?  Attempting to set the classpath the way I want it, save the
session, and reopen the session doesn't have the desired effect.  Sometimes
I even set the classpath, start a session, then go back to tweak the session
and my earlier changes are gone.  Am I doing this in the wrong order?

thanks
