After an AnyConnect Secure Mobility Client session expires and after a re-connect, the Windows 'focus' remains on AnyConnect. If I don't manually select a new window (the one I had been working in), hitting a CR triggers the AnyConnect default action which is "Disconnect". Very annoying.
I'm not suggesting changing the default action. But, once AnyConnect establishes a connection and shrinks itself to the Windows notification area, it seems it would be simple task to 'loose focus' (preferably restore focus to whatever the prior window was).
