seems to be what i would have expected...if [openpanel] thinks that  
the pwd is X, why should $(pwd) think it differently.

it does and it has been discussed multiple times on this list:
sending a command to the [shell] will start a new process (shell), run  
the command and quit. like it should be, child processes do not modify  
parent processes and siblings.
you could as well do: start a new xterm; notice that you are in  
${HOME}; run "cd /tmp"; close the xterm; start another xterm, notice  
that you are still in ${HOME}

i am not sure what you would like to achieve with [pwd] or [cd]
that is: if you could manage with [pwd] and [cd], why can't you do so  
with the current absolute/relative path in [openpanel]?
