Hello World on microbit not running when loaded

Greetings, I'm an experienced IT person with lots of microcontroller experience amongst other stuff over many years. But I thought I would follow the instructions to get started with my batch of microbits just delivered, ready for the Code Club I run, as this particular stuff is new to me.

So I followed the video, all fine including compiling the unmodified Hello World example. Then I drop the hex file onto the microbit folder, and the data starts to download (flashing led). Then at the end of the download the copied file vanishes, and it should, according to the video, start running. But instead nothing happens, and still nothing happens after a reset on the board.

Any ideas?

My setup is Firefox 49 under Ubuntu 16.04

'the copied file vanishes' -> this is correct. We only emulate a USB flash drive to make flashing easier. It's not actually stored.

Are you using https://developer.mbed.org/teams/microbit/code/microbit-hello-world/ ? I've just flashed it on a microbit and it runs fine (shows Hello World once on the display)...

Thanks, very strange. It worked under Ubuntu/Virtualbox/XP originally when it wouldn't under Ubuntu. But today it works under Ubuntu as well.
