i noticed that i can not change into "Dashboard, Explore, Trad, Transfer" i have to reload again. Maybe this is the crash you talked about?
Yes, that's the symptom that the js code has crashed.
You should see the errors once you open the js console in chrome.
Anyway, it might be the case that this particular issue is dependent on some other settings - I cannot recreate it on a different Win 7 machine.
But whatever it is in this case, it even enforces my point - we cannot rely on the devs testing the GUI before releasing it as they are not able to simulate all the different configurations.
Community testing should become part of the deployment cycle.
