Anat,
    You forgot to attach the 4 log files.   I'll need to see them to 
give you more help.
I was expecting this to be working with 3.2.0.

    Also see my comments below.

I saw references to the "AgentFrame" class in your wrapper.log.  I assumed

If it is not being shown, that should be fine.  I was thinking that that
