Test Studio has a problem with some of the elements we use in our PRPC HTML; I suspect some Silverlight controls that appear typically on Property popups. When I get such a popup and need to, for example, add a regular HTML element (like div or so) to my project, I perceive a very long delay of either no response or immediate unresponsiveness of the Test Studio.  For example, when I do “Locate in DOM” using the recorder when working with an input element, the results in the DOM window come back after a long time (I guess more than a minute, maybe a few minutes, it feels like if they should never come). Also when I do “Edit in Live”.
