Please describe your scenario in more detail. What is happening when you press the 'Tab' key via Test Studio? Ideally provide a test that demonstrates the issue, or point us to a public site that exhibits the behavior. Alternatively you can take a Fiddler trace using FiddlerCap
and send it to us in a zip file. Basically with that trace I'll try to "simulate" your app in order to reproduce the issue. A Jing video
demonstrating the issue may also help us to better understand what is happening.
If you feel any of this information is sensitive, you can submit a support ticket which is confidential, unlike this forum. Thanks for providing the info we need to best assist you.
