When I try the tool on N93 to test my app, and after I finished recording my action on executing the app, I try to press Edit+Call to stop the recording, but I failed on this. The key seemed useless and non-responding. And the program is tracked on the recording sceen no matter what I did except that I pressed the Cancel, which led to quit the test.

Now that the tool has such a problem, I wondered how to go on the test on N93. And I wondered if the tool is tested by developer before releasing it to let user test their app with it.
