Here is the Jing video of creating the new test script (WebTest Copy) from an existing one (WebTest), editing it and saving: http://screencast.com/t/HDFhJsoEJmP
I rebooted my computer, re-opened TestStudio. Here is the Jing video of examining the original and the new test script: http://www.screencast.com/t/GPhrh0TN
Note, after the reboot, the edits to "WebTest Copy" are missing.
The application log is attached.
