Meanwhile I've tried to use invisible Mode within other browsers with the newest Release (Q1/2011).
The issue in Firefox (Meanwhile Firefox 4) is still the same. The same issue occurs within Internet Explorer 7. Within the two Gecko Browsers (Chrome 11 and Safari 5) it works, but the browser keeps visible.
Settings mySettings = new Settings(BrowserType.Chrome, @"C:\browserlog\");
Manager myManager = new Manager(mySettings);
It would be great, if you could help me to get Invisible mode running succesful in any browser.
