SiteScope 11.12 64 bit installed on Windows server 2008 64 bit.
When trying to login to SiteScope and when opening the GUI or dashboard, SiteScope hangs and progress bar is showing, and stays at the same status.
To restart, the browser needs to be closed and opened up again.
This is a problem with the Java client used.
Make sure the JRE 6 is of update 027 or higher – there is a known published bug with JRE 24-26 which hangs the UI.
