Thanks for the post and question, and for your trial of WebUI Test Studio.
I tried the code you posted and it seemed to work for me in the latest version. So on top of the IE instance that is launched by WebUI, you are launching 2 other instances of IE?
Typically in WebUI, only one browser is launched at one time for a test unless popups are launched. If you decide to launch multiple browsers in one test, you would need to balance which browser is being used for the test steps in any one sequence.
So if you would like to continue with this type of testing, please try Manager.LaunchNewBrowser(BrowserType.InternetExplorer). The true arguement may be causing timeouts depending upon how long the ClientReadTimeout property is set to in the Manager.Settings object.
You can also try updating to the latest WebUI versions here
. If you decide to update, please uninstall the previous WebUi version for the Telerik Start Menu shortcut using the uninstall WebUI option.
Also let us know if you are using a version of Windows and IE other than the English (US) version.
