First I opened new test in qtp, then opened Internetexplorerbrowser and clicked on recording, opened IE and pasted https://login.yahoo.com/config/login_verify2?&.src=ym this and when login page opens entered username and password and clicked on signin button.
then stopped recording.
but in qtp it is recording till pasting https://login.yahoo.com/config/login_verify2?&.src=ym URL
after this what ever I do it is not recording.
