Screen Lock in Rev?

[Shani]

i use   put shell("batfile") into tProcess
answer tProcess

i use the stack which have text and add button. but the problem is that
when i use this  (put shell("batfile") into tProcess) it display the shell
and Agent but the stack is locked i cant do any thing with this.

i use
unlock screen
but it cant work.

i use JADE agents to connect with Rev, so that´s why i use bat file.
