Hi Steve, Have seen this before.. and yes the same - killing the task brought everything back to life. This is going back quite a while now, I think initially we put it down to a bug as we were on an early v8.0 firmware back then. But I think we also saw it just recently on a v9 firmware and it ended up being a windows xp firewall issue for us I believe. I will check with guy I was working with at the time and see if he remembers.... he will most likely respond to this post anyways... Will keep you posted. Regards Daniel Barichello.

Bring up taskman, kill nsauto.exe and presto - there's the desktop. Client seems to work fine afterwards so there's apparently no harm from killing it, but it's rather annoying. Anyone seen this and know how to cure it?
