iOS fast-forwards through all tracks & doesn't play any

Strange to hear / watch this happen:

Hit "Play" and nothing comes through the headphones (or speakers) at all; check the display and it's just zooming through all the tracks, spending less than a second before going to the next, over and over.

Mucked about for awhile and then came up with a theory:

It's due to the "Sound Check" feature, which I had just turned back on - and it now has to scan every single track to know what to do before it plays any.

Great background here: http://productionadvice.co.uk/sound-check-album-mode/

Sure enough, as soon as I let it go through all of them, it was able to play.

And then I turned "Sound Check" back off. :)

Has anyone seen some connection instability with the GlobalProtect VPN client (v1.2.2-14), on OS X 10.9 (Mavericks)?

Strangely, I see frequents drops of my entire WiFi connection (to an AirPort base station that's been solid before now) including to local (non-VPN'd) nodes as soon as I initiate the VPN connection (which also has been very solid before now).

Any clues?
