There are many applications (espcially common in CRM applications) which open popup windows in which the URL is the same as the parent window. The web server keeps track of the different windows using cookies or some other similar piece of data. Currently Test Studio cannot automate this scenario. It requires the URL of each browser window to be unique in order to detect the correct window in the "Connect to popup" window step.

Some ideas how to solve this include:
1) Ignore windows that Test Studio is already connected to
2) Look for some timer for how long the window has been open. Skip those longer than 30 seconds.
