WAC540 not showing all wireless clients

What exactly are you missing - probably overly tin-hat'ed mobile devices which make use of a private MAC (as Apple says) or a random MAC address (what the rest of the world does talk of) for this wireless ssid connection?

From wally brain, one thing I've observed (we're using Insight so could not care less) is that the "Recent Clients" can refer to number >5, but only five clients are listed, the scrolling (the grey control becomes visible the right of that box was and probably is still broken there. This is certainly a bug then.
