That&#x27;s a sort-of-misconception, I think. AFAIK the client has to &quot;advertise&quot; the general location of the standard buttons, so if it&#x27;s generally well-behaved, but just randomly locks up (via bug, not malicious intent), then you should generally still be able to close it.<p>(That&#x27;s my understanding from the pro-CSD crowd, I&#x27;m personally pro-SSD, so I may have misunderstood unintentionally, but I think I&#x27;m being as charitable as possible in the above interpretation&#x2F;description.)
