If I'm not mistaken there's an option for the Agent to ignore coordinates checking.
I believe that if you uncheck it, your script should run.
Just go here:
Options | Agent
In Agent Options window go to the Verification tab and uncheck the "Verify that coordinates passed to a method are inside the window". It should be 3rd item from the bottom.
This error is mostly observed when the script is trying to click a link, whose properties/attributes have changed.
Record the declarations of this particular link again and write a separate script which just clicks this link and you should be able to find the cause of this problem.
