Folks, Other then the below possibility, I've tried numerous attempts to duplicate this, on various platforms and machines, and simply cannot see the issue... the ONLY issue I noted was on one machine, after WIN 10 did it's auto update horror, and the player would NOT access ANY streams in ether EDGE or Firefox, but after rebooting that system, no issue.
By design, this is a responsive player. I don't remember the exact breakpoint, but I believe it's 524 pixels, the Volume Bar is sacrificed, as would a couple of other features if they were enabled... That also occurs on the 'pop-out' version... but it does that, as far as I know, and have observed, on all browsers, including Androids that I've checked.. that's by design,... is that what's happening?
