Interestingly when I changed connect to pop-up to code and wrote in the code below, test passed without a problem. But after closing browser windows and re-run of the test case it failed again and doesn't want to work again. How is that even possible?

Code:
// Connect to pop-up window : '/en/'
Manager.WaitForNewBrowserConnect("/en/", true, 15000);
Manager.ActiveBrowser.WaitUntilReady();

string navUrl = Convert.ToString(Data["extractedURL"]);

Log.WriteLine("------------------------------------------------------------");
Log.WriteLine("URL: " + navUrl);
Log.WriteLine("------------------------------------------------------------");
Log.WriteLine("Number of opened windows: " + Manager.Browsers.Count());
Log.WriteLine("------------------------------------------------------------");

Uri url1 = new Uri(navUrl);

ActiveBrowser.Window.Maximize();

ActiveBrowser.NavigateTo(url1, true);

Log.WriteLine("------------------------------------------------------------");
Log.WriteLine("Number of opened windows: " + Manager.Browsers.Count());
Log.WriteLine("------------------------------------------------------------");

Hi Daniel,

OK, here are the steps before the error occurs:
1. navigate to test event
2. choose exact event
3. choose delivery type
4. choose payment type
5. right click on a logo
6. left click on Open link in a new window (I used blind mouse click)
7. connect to pop-up
8. coded step: navigate to specific URL

Everything is working fine until step 8. Check link to video below for more details and I apologise for having no sound.
